The Messenger of Allah ﷺ said, "There is an hour in Friday during which no Muslim, if he happens upon it while asking his Lord for something, fails to be granted it."
وقال رسول الله ﷺ في الجمعة ساعة لا يوافقها مسلم وهو يسأل ربه شيئا إلا آتاه إياه
This is a sahih hadith, found in al-Sahifah al-Mufradah under number 7. It has already been reported repeatedly in similar form through various routes from Abu Hurairah, first at 7151, where we explained that it was reported by the whole group, but the two Shaykhs did not report it through the route of al-Sahifah, rather they reported it through other routes. It is found in Muwatta, page 108, in the recension of al-Araj. See also 7810, 7811, 8088, and see as well the two supplementary notes 3242 and 3560.
