When My servants ask thee concerning Me, I am indeed close (to them): I listen to the prayer of every suppliant when he calleth on Me: Let them also, with a will, listen to My call, and believe in Me: That they may walk in the right way.[Qur'an 2:186]
Narrated 'Aisha(RA): Whenever Allah's Apostle(PBUH) ordered the Muslims to do something, he used to order them deeds which were easy for them to do, (according to their strength 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."
