Translation of the verse 9 from Surah Yusuf : Number of verses 111 - - page 236 - Part 12.
"Kill Yusuf (Joseph) or cast him out to some (other) land, so that the favour of your father may be given to you alone, and after that you will be righteous folk (by intending repentance before committing the sin)."
Kill Joseph or cast him out to [another] land; the countenance of your father will [then] be only for you, and you will be after that a righteous people."
(12:9) Let us, therefore, kill Joseph or throw him somewhere so that your father's attention should be turned exclusively towards you. After this, you should again become righteous people. " *10
*10) This sentence depicts the true psychology of those people who give themselves up to the lusts of their hearts, and, at the same time, do not want to break away completely from faith and religion. This is how a person of this type behaves. Whenever he is tempted to do a certain evil thing, he makes up his mind to do it first and puts off the demands of his faith for the time-being. And if his conscience pricks him, he tries to soothe it, saying, "Have a little patience. Let me first do this evil thing, which is an obstacle in my way. Then I will repent and become as good as Thou desirest to see me." As the brothers of Prophet Joseph belonged to this type, they soothed their pricking consciences, saying, "After doing away with Joseph, who is the chief obstacle in our way, we will again become righteous."
