The Messenger of Allah ﷺ said, "There is an hour on Friday during which, if a Muslim happens to be standing in prayer asking Allah for some good, He will surely grant it to him." And he indicated with his hand how brief it is.
حدثنا محمد بن الصباح أنبأنا سفيان بن عيينة عن أيوب عن محمد بن سيرين
قال رسول الله ﷺ إن في الجمعة ساعة لا يوافقها رجل مسلم قائم يصلي يسأل الله فيها خيرا إلا أعطاه وقللها بيده
