Narrated 'Aisha: Whenever Allah's Apostle ordered the Muslims to do something, he used to order them deeds which were easy for them to do, (according to their strength and endurance). They said, O Allah's Apostle! We are not like you. Allah has forgiven your past and future sins. So Allah's Apostle became angry and it was apparent on his face. He said, I am the most Allah fearing, and know Allah better than all of you do.
