Concerning the Night of Power
It is related from ʿÁyesha that, 'The Apostle of God said, "Seek the night of power in the odd nights of the last ten days of the month Ramaḍán."'—At Bukhárí.
It is related from Ubádah bin Ṣámit that he said, 'The Prophet came out to inform us of the night of power; and two men of the Muslims were disputing together, and he said, "I came out to inform you of the night of power, and such-and-such an one were disputing together, and it was taken away (from my memory). And perhaps it is better for you; therefore seek it in the ninth and seventh and fifth."'—Al Bukhárí.
On Seclusion for Religious Exercises
It is related from Abú Hurairah that, 'The Qurʾán was recited to the Prophet once every year, but it was recited twice to him during the year in which he died. And he used to seclude himself each year for ten days; but he secluded himself for twenty days during the year in which he died.'—Al Bukhárí.
It is related from Anas that, 'The Prophet used to seclude himself during the last ten days of Ramaḍán; but one year he did not seclude himself, and when the following year came round he secluded himself twenty days.'—At Tirmidhí.
It is related trom ʿÁyesha that she said, 'It is the rule that they who seclude themselves should not visit the sick, nor be present at funerals, nor touch a woman, nor live with her, nor go out for any purpose except what is indispensably necessary. And there is no seclusion apart from fasting, and there is no seclusion except in a mosque.'—Abú Dáud.
