Sayyiduna Abu Bakrah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "No person should ever say, 'I fasted the entire Ramadan and performed voluntary prayers throughout the whole Ramadan.'" The narrator says: I do not know whether the Prophet (peace and blessings be upon him) disliked expressing one's acts of worship, or whether he (peace and blessings be upon him) meant to say that a person should also sleep during Ramadan.
