So Yusuf (Joseph) began to search their sacks before his brother’s. Then (at last) he took (the goblet) out of his (real) brother’s (Benjamin’s) sack. That is how We revealed to Yusuf (Joseph) the plan. He could not have held his brother (as a captive) under the law of the King (of Egypt) except (as) Allah wills. We exalt in ranks whom We like. And above every possessor of knowledge is (also) One possessing greater knowledge.
