Yusuf 12:9

Oqtuloo yoosufa awi itrahoohuardan yakhlu lakum wajhu abeekum watakoonoo min baAAdihiqawman saliheen

Kill Joseph or cast him out to [another] land; the countenance [i.e., attention] of your father will [then] be only for you, and you will be after that a righteous people."

Let us kill Yūsuf, or throw him at some place on earth, and thus your father’s full attention will be devoted for you alone, and after doing that, you may become a righteous people.’’
