I heard the Prophet ﷺ say, "There is an hour during the night in which no Muslim man asks Allah for something good concerning this world or the hereafter without Allah granting it to him, and this happens every night."
سمعت النبي ﷺ يقول: إن في الليل لساعة لا يوافقها رجل مسلم يسأل الله خيرا من أمر الدنيا والآخرة إلا أعطاه إياه وذلك كل ليلة.
Muslim narrated it in "The Prayer of Travelers" (757:166) from Uthman bin Abu Shayba, from Jareer, from Amash, from Abu Sufyan, from Jabir, and he related it.His saying, "There is indeed an hour in the night," may refer to the last third of the night, as mentioned in other hadiths.
