The Messenger of Allah ﷺ said, "Friday contains twelve hours, and there is not a Muslim servant who asks Allah for something during one of them except that He grants it to him. So seek it in the final hour after the Asr prayer."
أخبرنا عمرو بن سواد بن الأسود بن عمرو والحارث بن مسكين قراءة عليه وأنا أسمع واللفظ له عن ابن وهب عن عمرو بن الحارث عن الجلاح مولى عبد العزيز أن أبا سلمة بن عبد الرحمن حدثه
عن رسول الله ﷺ قال يوم الجمعة اثنتا عشرة ساعة لا يوجد فيها عبد مسلم يسأل الله شيئا إلا آتاه إياه فالتمسوها آخر ساعة بعد العصر
Its isnad is sahih. Abu Dawud narrated it in the Book of Prayer, chapter on which hour of Friday is the hour when supplications are answered, hadith 1048, from the hadith of Ibn Wahb, with the same wording. It is also found in al-Kubra, hadith 1697. Hakim graded it sahih according to the criteria of Muslim (1/279), and Dhahabi agreed with him.
