Mukhtasar Bukhari

Narrated Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "No one will be saved because of his deeds (rather, it will be by Allah's mercy)." The people asked, "Not even you, O Messenger of Allah?" The Messenger of Allah (peace and blessings of Allah be upon him) replied: "Not even me, unless Allah's mercy envelops me." And he said: "Act with moderation, seek closeness to Allah, and worship in the morning, evening, and a part of the night, and acting with moderation will lead you to your desired destination (i.e., Paradise)."

Narrated from Ummul Momineen Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) was asked: Which deed is most beloved to Allah Almighty? He replied: "That deed which is done consistently, even if it is little."
