(5:48)And unto you (O Prophet) have We vouchsafed this divine writ, setting forth the truth, confirming the truth of whatever there still remains of earlier revelations and determining what is true therein ... Unto Every One of you We appointed a (different) Law and a way of life. And if God had so willed. he would surley have made you all one single community: but (He willed it otherwise) in order to test you by means of what He has vouchsafed unto you. Vie, then, with one another in doing good works! Unto God you all must return: and then He will make you truly understand all that on which you used to differ.

.... this Verse which Allah (Swt) mentions in the Quran that the Belief in One God, Angels and Paradise and Hell, is all the Same delivered by All Prophets, but where the change takes place is in the Law as given by God to various communities throughout the history depending on their environment and development of their mind and body....
At the time of Prophet Yusuf (Alaihi Salaam) there was a law that if someone was to get caught stealing will be enslaved or sold as a slave. When Yusuf (alaihi Salaam's) brother Benjamin was caught with a cup inside his bag his price that he paid for that incident was to become a slave of Yusuf (alaihi Salaam).
(12:74) The officials said: "If you are lying, what will be the penalty for him who has stolen?"
(12:75) They replied: "He in whose saddlebag the cup is found, he himself shall be its recompense." Thus do we punish the wrong-doers.
These people in Egypt at that time were from the people of Ibrahim (Alaihi Salaam). This was the customary punishment amongst the Hebrews at that time for stealing. This is also confirmed in Book of Exodus Chapter 23 Verse 3.
So from the time of Adam and Eve (Alaihi Salaam) there has been variations in the religious laws. We don't know exactly what was the law back then.
