Sayyiduna Zaid bin Thabit (may Allah be pleased with him) narrates that we were commanded to recite «‏‏‏‏سُبْحَانَ اللَٰه» ‏‏‏‏ thirty-three times, «‏‏‏‏الحَمْدُ لِلَٰه» ‏‏‏‏ thirty-three times, and «‏‏‏‏اللهُ أَكْبَرُ» ‏‏‏‏ thirty-four times after every prayer. Then an Ansari man saw a dream in which it was said to him, "Has the Messenger of Allah (peace and blessings be upon him) commanded you to recite tasbih this many times after every prayer?" He replied, "Yes." (The person who came in the dream) said, "You should recite it twenty-five times each and include tahlil «‏‏‏‏لَا إِلٰهَ إِلَّا الله» ‏‏‏‏ in it." When morning came, that man went to the service of the Prophet (peace and blessings be upon him) and informed him of the entire matter. The Messenger of Allah (peace and blessings be upon him) said, "Do it that way."
