Th also mentions رَدَأَ and رَدِىءَ as meaning the same as رَدُؤَ, but these are strange.
More strange is what is said in the Msb: رَدَا, ism fāʿil رَدِىٌّ, [given as a variant of dialect,] which IDrst, in his commentary on the Fs, says is wrong and belongs only to the common people.
Said of a man as well: see رَدِىْءٌ, its ism fāʿil. [Also disapproved, disliked, hated, or abominable: see رَدِىْءٌ.]

(M.) Hence, (T,) رَدَأَهُ بِهِ He strengthened and supported him, or it, by means of it, (Lth, T, M, * K,) namely, a person by a thing, (Lth, T,) or a thing by a thing, (M,) like as one strengthens and supports a wall by means of a structure which he attaches thereto; (T;) as also ارادأهُ . (T, * K.)
