Muḥammad b. Yaḥyā and Aḥmad b. Idrīs, from Muḥammad b. Aḥmad, from whoever he mentioned, from Muḥammad b. al-Fuḍayl, from Isḥāq b. ʿAmmār, from Abī ʿAbd Allāh عليه السلام, who said: “There was a Prophet among the Children of Israel to whom Allāh had promised that He would help him in fifteen nights, but when he informed his people of that, they said: “By Allāh, when it happens, He will surely do such-and-such and such-and-such.” So, Allāh delayed it for fifteen years. There was another among them whom Allāh promised victory within fifteen years. When the Prophet عليه السلام informed his people of that, they said: “It is as Allāh has willed,” so Allāh hastened it for them to fifteen nights.”
