Core sense — he ate fruit; he jested; he wondered at it; he repentedgenerated
5.1
He ate fruit; and he took fruit with his hand, helping himself to it; synonymous with تَنَاوَلَ الفَاكِهَةَ.
Hence, as is said in the A, the saying in the Kur [56:65], فَظَلْتُمْ تَفَكَّهُونَ, is ironical, meaning [And then you would be in the condition of] making your fruit to be your saying إِنَّا لَمُغْرَمُونَ Truly we are burdened with debt (words which occur in the next verse).
Or تَفَكَّهَ here — or rather in a case of this kind — means he threw the fruit away from himself; so says Ibn-ʿAteeyeh in his exposition. [But see the other explanations that follow.]
It also means he abstained from fruit; so it bears two opposite meanings.
5.1.1figurative · مجاز
Sometimes it means he amused himself with talk, as one amuses oneself with eating fruit after a meal; that is, التَّفَكُّهُ is used figuratively as meaning التَّنَقُّلُ بِالحَدِيثِ.

5.1.4figurative · مجاز — inferredhe enjoyed it—تفكّه بِهِ
Particularly, he enjoyed eating it.
5.1.5figurative · مجاز — inferredhe wondered at it—تفكّه
Construed with مِنْهُ. And so فَكِهَ, likewise followed by منه.
Hence, according to some, the saying in the Kur cited above, فَظَلْتُمْ تَفَكَّهُونَ, means [And then you would be in the condition of] wondering at what had befallen you in respect of your seed-produce.
5.1.6
He repented, grieved, lamented, or regretted.
As explained by some, the words of the Kur cited just above mean [And then you would be in the condition of] repenting, and so on.
And so تَفَكَّنُونَ, which is of the dialect of ʿOkl; or, according to Lh, Temeem say تَتَفَكَّنُونَ and Azd-Shanooʾah say تَتَفَكَّهُونَ.

He ate fruit ( فَاكِهَة ): (Msb, K:) and He took fruit with his hand, [he helped himself to it;] syn. تَنَاوَلَ الفَاكِهَةَ : and hence, as is said in the A, (TA,) the saying in the Kur [lvi. 65], فَظَلْتُمْ تَفَكَّهُونَ is ironical, meaning [And then ye would be in the condition of] making your fruit to be your saying إِنَّا لَمُغْرَمُونَ Verily we are burdened with debt (which words occur in the next verse)]: or تَفَكَّهَ here [or rather in a case of this kind] means He threw away from himself the fruit: thus says Ibn-'Ateeyeh, (K, TA,) in his exposition: (TA:) [but see other explanations in what follows:] and it signifies also He abstained from fruit: thus it bears two contr. meanings. (K.) And sometimes [it means He amused himself with talk; like as one amuses himself with the eating of fruit after a meal; i. e.] التَّفَكُّهُ is metaphorically used as meaning التَّنَقُّلُ بِالحَدِيثِ . (Bd in lvi. 65.) And He affected jesting, or joking. (TA.) And تفكّهوا بِفُلَانٍ They spoke evil of such a one; or did so in his absence; and defamed him; and did thus with jesting, one with another. (TA.) And تفكّه بِهِ He enjoyed it: (S, Msb, K:) and [particularly] (Msb) he enjoyed the eating of it. (Mgh, Msb.) And تفكّه also signifies He wondered, (S, Msb, K,) مِنْهُ at it; and so فَكِهَ , followed likewise by منه . (K.) And hence [accord. to some] the saying in the Kur cited above, فَظَلْتُمْ تَفَكَّهُونَ i. e. [And then ye would be in the condition of] wondering at what had befallen you in respect of your seed-produce. (TA.) And He repented, grieved, lamented, or regretted: (IAar, S, K:) and the words of the Kur cited in the last sentence above, (S, TA,) as expl. by some, (TA,) mean [And then ye would be in the condition of] repenting, &c.: (S, TA:) and so تَفَكَّنُونَ , which is of the dial. of 'Okl; or, accord. to Lh, Temeem say تَتَفَكَّنُونَ , and AzdShanoo-ah say تَتَفَكَّهُونَ . (TA.)
