Is it narrated from the Prophet (peace be upon him) that we should say: "Subhan Allah, Walhamdulillah, Wala Ilaha Illa Allah, Wallahu Akbar" (Glory be to Allah, and all praise is due to Allah, and there is no god but Allah, and Allah is the Greatest) 25 times? And is it true that the Prophet approved of this after a man saw it in a dream?

The aforementioned hadith was reported by Ahmad, An-Nasa'i, and others, on the authority of Zayd ibn Thabit, may Allah be pleased with him. Its wording states that they (the Companions) were commanded to say "Subhan Allah" (glory be to Allah) 33 times after every prayer, "Alhamdulillah" (praise be to Allah) 33 times, and "Allahu Akbar" (Allah is the Greatest) 34 times. Then, a man from the Ansar had a dream in which he was told, "Make them 25 and include 'La ilaha illa Allah' (there is no god but Allah) in them." When he awoke, he mentioned this to the Prophet, peace and blessings be upon him, who then said: "Make them so." The chain of narration of this hadith is authentic, and Al-Albani graded it as authentic.
