Core sense — the side, or corner, of a thing; a support; a strong people or partygenerated
1the side, or outward part, of a thing—جَانِب
Or the strongest جَانِب, that is, the strongest side, or outward part, of a thing of any kind.
the corner, or angle, of a house or room or the like—زَاوِيَة
K in art. زوى. This is perhaps what is meant by the strongest جانب, since the strongest outward part of a house is certainly the corner: so the angle of the Kaabeh in which the Black Stone is set is specially called رُكْنُ البَيْتِ, that is, رُكْنُ بَيْتِ ٱللّٰهِ.
The رُكْن of a قَصْر [or palace, or pavilion, etc.] is its جَانِب, or its strongest جانب, and so of a mountain. See رَكُنَ and رَكِينٌ.
The plural is أَرْكَانٌ and أَرْكُنٌ, each properly a plural of paucity, but the former is used as a plural of multitude.
The أَرْكَان of anything are its جَوَانِب, the sides, or outward parts, or the corners, on which it rests and by which it is supported.
The أَرْكَان of a land are its far parts, its sides or corners.
1.1figurative · مجاز — inferredI looked for a blessing by means of him, or it—تَمَسَّحْتُ بِأَرْكَانِهِ
Hence, a stay, or support, of any kind: see an example under مِرْجَمٌ.
Its meaning is تَبَرَّكْتُ بِهِ.
Also a thing by which one is strengthened, such as dominion, an army or military force, and the like.
and he turned away from belief with his forces—فَتَوَلَّى بِرُكْنِهِ
So it has been explained in the Qur 51:39, his forces being to him like the رُكْن properly so termed.
Also a man's kinsfolk, or his nearer or nearest relations, his clan or tribe; syn. عَشِيرَةٌ; his people or party, and the higher among them, and those by whom he is aided and strengthened. ISd thought it so called by way of comparison to a رُكْن properly so termed.
or that I might have recourse to a strong people, or party—أَوْ آوِىَ رُكْنٍ شَدِيدٍ
So it has been explained in the Qur 11:82; or it there means عَشِيرَة.
he is a noble, one of the nobles of his people—هُوَ رُكْنٌ مِنْ أَرْكَانِ قَوْمِهِ
the limbs of a man, with which he gains or works, such as the arms and the legs—أَرْكَانُ الإِنْسَانِ
1.2figurative · مجاز — inferredhe has recourse to strong might and resistance—هُوَ يَأْوِى إِلَى رُكْنٍ شَدِيدٍ
So it has also been explained in the words of the Qur last cited above.
Also might, and resistance.
1.3figurative · مجاز — inferred
Also a thing, an affair, a case, an event, or an action of great magnitude or moment: momentous, formidable, or terrible.
AHeyth explains it in this way in the saying of En-Nábighah [Edh-Dhubyánee]:
shāhidلَا تَقْذِفَنِّى بِرُكْنٍ لَا كِفَآءَ لَهُ
[By no means reproach me with a momentous, or a formidable, thing or action, an enormity that has no equal; though, he goes on to say, the enemies incite you, with companies of men aiding one another].
1.4figurative · مجاز — inferredthe essence of a thing; that by which a thing subsists—رُكْنُ الشَّىْءِ
In the conventional language of the schools. It is from التَّقَوُّمُ, because the قِوَام, or subsistence, of the thing is by its رُكْن, not from القِيَام; otherwise the agent would have to be a رُكْن to the action, and the substance to the accident, and the thing to which a quality is attributed to the quality. It is that without which the thing has no subsistence.
It is also applied to an essential part of the thing, that is, a part of the مَاهِيَّة, or essence, of the thing (Kull; and أَرْكَانُ الشَّىْءِ is likewise explained in the Msb as the parts of the ماهيّة of the thing), as when we say that القِيَام is a رُكْن of الصَّلَاْة; and it is applied as well to the whole مَاهيّة of the thing.
أَرْكَانُ العِبَادَاتِ means the fundamentals of the services of religion, by the neglect, or non-observance, of which they are ineffectual or void.
Or, as some say, رُكْنُ الشَّىْءِ means that by which the thing is complete, and this is intrinsic to it, unlike its شَرْط, or condition, which is outside it.
Qur’ānic occurrences رُكْن
11:80
قَالَ لَوْ أَنَّ لِى بِكُمْ قُوَّةً أَوْ ءَاوِىٓ إِلَىٰ رُكْنٍ شَدِيدٍHe said: "Would that I had power to suppress you or that I could betake myself to some powerful support."

The جَانِب [meaning side, or outward part,] of a thing: (Msb:) or the strongest جَانِب [i. e. side, or outward part,] (S, K, TA) of a thing (S, TA) of any kind: (TA:) the corner, or angle, ( زَاوِيَة ,) of a house or room or the like: (K in art. زوى :) [and this is perhaps what is meant by the “ strongest جانب ; ” for the strongest outward part of the house is unquestionably the corner, or angle: thus the angle in which is the Black Stone, of the Kaabeh, is specially called رُكْنُ البَيْتِ , i. e. رُكْنُ بَيْتِ ٱللّٰهِ :] the رُكْن of a قَصْر [or palace, or pavilion, &c.,] is its جَانِب [or its strongest جانب ], and so of a mountain: (TA: [see رَكُنَ , and رَكِينٌ :]) the pl. is أَرْكَانٌ and أَرْكُنٌ [each properly a pl. of pauc., but the former is used as a pl. of mult.]: (Msb, TA:) the أَرْكَان of anything are is جَوَانِب [or sides, or outward parts, or its corners, or angles,] upon which it rests, and by which it is supported: (TA:) and the أَرْكَان of a land are its extremities [or sides or corners]. (Ham p. 478.) [Hence, A stay, or support, of any kind: see an ex. voce مِرْجَمٌ : whence, perhaps,] one says, تَمَسَّحْتُ بِأَرْكَانِهِ , meaning تَبَرَّكْتُ بِهِ [i. e. I looked for a blessing by means of him, or it]. (TA.) A thing whereby one is strengthened ( مَا يُقَوَّى بِهِ [in the CK ما تَقَوَّىبه ]), such as dominion ( مُلْك [in the CK مَلِك ]), and an army, or a military force, &c.: (K:) and thus it has been explained as occurring in the Kur [li. 39], where it is said, فَتَوَلَّى بِرُكْنِهِ , (TA,) i. e. And he turned away from belief with his forces; because they were to him like the رُكْن [properly so termed]. (Jel.) A man's kinsfolk; or nearer, or nearest, relations; or clan; or tribe; syn. عَشِيرَةٌ : (AHeyth, TA:) a man's people, or party; and the higher among them; and the persons by whom he is aided and strengthened: thought by ISd to be thus called by way of comparison [to a رُكْن properly so termed]: and thus it has been explained as used in the Kur [xi. 82], where it is said, أَوْ آوِىَ رُكْنٍ شَدِيدٍ [Or that I might have recourse to a strong people, or party, &c.]: (TA:) or it here means عَشِيرَة [explained above]. (Jel.) And A noble, or high, person; as in the saying, هُوَ رُكْنٌ مِنْ أَرْكَانِ قَوْمِهِ [He is a noble, of the nobles of his people]. (TA.) And أَرْكَانُ الإِنْسَانِ means The members, or limbs, of the man, with which things are gained or earned, or with which he works; as the hands or arms, and the feet or legs. (TA.) Also Might, and resistance: (S, K:) so in the saying, هُوَ يَأْوِى إِلَى رُكْنٍ شَدِيدٍ [He has recourse to strong, or vehement, might and resistance]: (S:) and so it has been explained as used in the words of the Kur last cited above. (TA.) And A thing, an affair, a case, an event, or an action, of great magnitude or moment, momentous, formidable, or terrible. (AHeyth, K.) Thus AHeyth explains it as used in the saying of En-Nábighah [Edh-Dhubyánee], 1 [By no means reproach thou me with a momentous, or a formidable, thing or action, or an enormity, that has not its equal; though (he proceeds to say) the enemies incite thee, with companies of men aiding one another]. (TA.) لَا تَقْذِفَنِّى بِرُكْنٍ لَا كِفَآءَ لَهُ In the conventional language [of the schools], رُكْنُ الشَّىْءِ means [The essence of the thing; or] that whereby the thing subsists: from التَّقَوُّمُ ; because the قِوَام [or subsistence] of the thing is by its رُكْن : not from القِيَام : else it would necessarily be the case that the agent would be a رُكْن to the action; and the substance, to the accident; and the thing to which a quality is attributed, to the quality: (KT:) it is that without which the thing has no subsistence: (Kull:) and is [also] applied to [an essential, or essential part, of the thing; i. e.,] a part of the مَاهِيَّة [or essence] of the thing, (Kull, [and in like manner أَرْكَانُ الشَّىْءِ is explained in the Msb as meaning the parts of the ماهيّة of the thing,]) as when we say that القِيَام is a رُكْن of الصَّلَاْة ; as well as to the whole مَاهيّة [of the thing]: (Kull:) [thus] أَرْكَانُ العِبَادَاتِ means the fundamentals [or essentials] of the services of religion, by the neglect, or non-observance, of which they are ineffectual, or null, or void: (TA:) or, as some say, رُكْنُ الشَّىْءِ means that whereby the thing is complete; and this is intrinsic therein; differing from the شَرْط [or condition] thereof, which is extrinsic thereto. (KT.)
