It is narrated from Hazrat Anas (may Allah be pleased with him) that a man came to the service of the Prophet (peace and blessings be upon him) and said, "O Messenger of Allah (peace and blessings be upon him)! Tell me how many prayers Allah has made obligatory?" The Prophet (peace and blessings be upon him) said, "Allah has made five prayers obligatory upon His servants." He asked, "Is there any prayer obligatory before or after these?" The Prophet (peace and blessings be upon him) replied three times, "Allah has made five prayers obligatory upon His servants." Upon this, the man said, "By Him Who sent you with the truth, I will neither decrease nor increase anything in them." The Prophet (peace and blessings be upon him) said, "If he is truthful, he will enter Paradise."
