Sayyiduna Abu Bakr (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "None of you should ever say that I have fasted the entire Ramadan or that I have stood (in prayer) the entire Ramadan. And Allah knows best. The Prophet (peace and blessings be upon him) disliked that his Ummah declare themselves pure or righteous, or he said that sleep or heedlessness is inevitable (it does happen)."
