أَيَّانَ ذ , (T, S, M, &c.,) of the measure فَعَّال, or it may be of the measure فَعْلَان, (Msb,) also pronounced ↓ اـِيَّانَ, (T, S, M, K,) the latter of the dial. of Suleym, mentioned by Fr, (T, S,) and by Zj, (M,) is an interrogative respecting a time, (T, S, Msb,) but only respecting a time not come: (T:) signifying When? (S, M, Msb;) at what time? (Msb, K:) it is fem.; but may be made masc.: (Lh, M:) and it may be pronounced with imáleh, though not belonging to a class of words regularly subject to imáleh. (TA.) It is said in the Kur [xvi. 22 and xxvii. 67], accord. to different readings, أَيَّانَ يُبْعَثُونَ or ↓ اـِيَّانِ [ When they shall be raised to life ]; (T, S, M;) i. e. when shall be the resurrection. (Aboo-Is-hák, T.) But you may not say, أَيَّانَ فَعَلْتَ ذَاكَ as meaning When didst thou that? (T.) ― -b2- IJ says that, were it syn. with مَتَى, it would be conditional; whereas it was not mentioned by his colleagues among the adverbs used conditionally, as مَتَى and أَيْنَ &c.: but sometimes it has a conditional meaning, though that meaning be not explicit. (M.) A poet says, أَيَّانَ نُؤْمِنْكَ تَأْمَنْ غَيْرَنَا وَ اـِذَا لَمْ تُدْرِكِ الأَمْنَ مِنَّا لَمْ تَزَلْ حَذِرَا [ When we grant thee security, thou wilt be secure from others than us; and when thou obtainest not security from us, thou wilt not cease to be in a state of fear ]. (I 'Ak p. 300.)
