So he began [the search] with their bags before the bag of his brother; then he extracted it from the bag of his brother. Thus did We plan for Joseph. He could not have taken his brother within the religion [i.e., law] of the king except that Allāh willed. We raise in degrees whom We will, but over every possessor of knowledge is one [more] knowing.1
Translation: Saheeh International (English)
1 Ending with the ultimate knowledge of Allāh (subḥānahu wa taʿālā).
So they returned them to Joseph to inspect their bags. He started by inspecting the bags of his half-brothers before inspecting the bag of his full brother, to cover up what he was doing. Then he inspected the bag of his full brother, and took the bowl of the king out of it. As Allah planned things for Joseph by arranging to have the bowl put into the bag of his brother, He also arranged – for the benefit of Joseph – that his brothers would be given the punishment of their country, which was the enslavement of the thief. This would not have come to pass if it had been according to the punishment of the king for thieves, which was beating and fining. Allah is able to arrange matters in whatever way He wills. He raises the ranks of those of His servants whom He wills, as He raised the rank of Joseph. Above every possessor of knowledge is someone more knowledgeable than them, and above the knowledge of everyone is the knowledge of Allah, Who knows all things.
