Abu Tha'laba al-Khushani reported God’s messenger as saying, “God has made certain things binding, so do not cause them to be lost; He has prohibited certain things, so do not violate them; He has fixed certain limits, so do not transgress them; and He, without being forgetful, has said nothing about certain things, so do not search into them.”
Jabir told how ‘Umar b. al-Khattab brought God’s messenger a copy of the Torah saying, “Messenger of God, this is a copy of the Torah.” When he received no reply he began to read to the obvious displeasure of God’s messenger, so Abu Bakr said, “Confound you 1 do you not see how God’s messenger is looking?” So ‘Umar looked at God’s messenger’s face and said, “I seek refuge in God from the anger of God and His messenger. We are satisfied with God as Lord, with Islam as religion, and with Muhammad as Prophet.” Then God’s messenger said, “By Him in whose hand Muhammad’s soul is, were Moses to appear to you and you were to follow him and abandon me, you would err from the right way. Were he alive and came in touch with my prophetic mission he would follow me.”
