(And when they came unto their father and had spoken thus to him) he said: Nay, but your minds have beguiled you into something. (My course is) comely patience! It may be that Allah will bring them all unto me. Lo! He, only He, is the Knower, the Wise.
So, when they despaired of (moving) him, they conferred together apart. The eldest of them said: Know ye not how your father took an undertaking from you in Allah's name and how ye failed in the case of Joseph aforetime? Therefore I shall not go forth from the land until my father giveth leave or Allah judgeth for me. He is the Best of Judges.
They said: If he stealeth, a brother of his stole before. But Joseph kept it secret in his soul and revealed it not unto them. He said (within himself): Ye are in worse case and Allah knoweth best (the truth of) that which ye allege.
Then he (Joseph) began the search with their bags before his brother's bag, then he produced it from his brother's bag. Thus did We contrive for Joseph. He could not have taken his brother according to the king's law unless Allah willed. We raise by grades (of mercy) whom We will, and over every lord of knowledge there is one more knowing.
