Sahih Bukhari

Whenever Allah's Messenger (ﷺ) ordered the Muslims to do something, he usedto order them deeds which were easy for them to do, (according totheir strength and endurance). They said, "O Allah's Messenger (ﷺ)! We are notlike you. Allahhas forgiven your past and future sins." So Allah'sApostle became angry and it was apparent on his face. He said, "I amthe most Allah fearing, and know Allah better than all of you do."
