اضلّهُ
1.
, verbal noun إِضْلَالٌ, He, or it, made him, or caused him, to err, stray, or go astray; to deviate from the right way or course, or from that which was right; to miss, or lose, the right way; or to lose his way. (Az, TA.) [See also 2, first sentence.] الإِضْلَالُ is of two sorts: one of these is the consequence of erring, or straying; either as in the case in which one says أَضْلَلْتُ البَعِيرَ (explained above, see 1, former half); or the decreeing that one shall err, or stray, &c., because he has done so already, and this is sometimes the case when the إِضْلَال of a man is attributed to God: the other sort is the embellishing [or commending] to a man that which is false, or wrong, or vain, in order that he may err, or stray, &c.: and God's إِضْلَال of a man is of two sorts; one of which has been explained above; the other is God's so constituting man that when he observes [and pursues] a certain course, or way, [of acting or the like], whether it be such as is commended or such as is discommended, he habituates himself to it, and esteems it pleasant, and keeps to it, and finds it difficult to turn from it, wherefore it is said that custom is a second nature. (Er-Rághib, TA.)

Also He, or it, made, or caused, him, or it, to perish, or become lost; synonym أَهْلَكَهُ, (S, TA,) and أَضَاعَهُ, (El-Fárábee, S, O, Msb,) or ضَيَّعَهُ; (TA;) [اضاعهُ and ضيّعهُ signifying the same; and so اضلّهُ and
ضللّٰهُ; whence,] أَلَمْ يَجْعَلْ كَيْدَهُمْ
فِى تَضْلِيلٍ, in the Qur'an, 105:2, means [Did He not make their plot to be such as ended] in a causing to perish, or become lost, (فِى تَضْيِيعٍ,) and in annulment? (Ksh, Bd.) أَضَلَّ أَعْمَالَهُمْ, in the Qur'an, 47:1 and 9, which may be rendered (assumed tropical:) He will cause their works to be lost, or to be of no effect], means, according to Aboo-Is-hák, He will not recompense them for their good works; the phrase being similar to the saying قَدْ ضَلَّ سَعْيُكَ [explained above]. (TA.) And أَضَلَّ اللّٰهُ ضَلَالَكَ (assumed tropical:) [May God make thine erring to be no more, or to come to an end,] is explained by ISk as meaning may thine erring pass away from thee, so that thou shalt not err; and he adds that the saying مَلَّ مَلَالُكَ means ذَهَبَ
عَنْكَ حَتَّى لَا تَمَلَّ. (TA.)
