The boy and the king
Suhaib reported that Allah's Messenger (may peace be upon him) thus said: There lived a king before you and he had a (court) magician. As he (the magician) grew old, he said to the king: I have grown old, send some young boy to me so that I should teach him magic. He (the king) sent to him a young man so that he should train him (in magic). And on his way (to the magician) he (the young man) found a monk sitting there. He (the young man) listened to his (the monk's) talk and was impressed by it. It became his habit that on his way to the magician he met the monk and set there and he came to the magician (late). He (the magician) beat him because of delay.
