﴿ ٱقْتُلُوا۟ يُوسُفَ أَوِ ٱطْرَحُوهُ أَرْضًۭا يَخْلُ لَكُمْ وَجْهُ أَبِيكُمْ وَتَكُونُوا۟ مِنۢ بَعْدِهِۦ قَوْمًۭا صَٰلِحِينَ ﴾

“[Said one of them:] "Slay Joseph, or else drive him away to some [faraway] land, so that your father's regard may be for you alone: and after this is done, you will be [free to repent and to live once again as] righteous people!"”

Then they said to one another: (Kill Joseph or cast him to some (other) land) in a pit, (so that your father's favour may be all for you) so that your father may turn entirely to you, (and (that) ye may afterward) after killing him (be righteous folk) repentant for killing him; it is also said that this means: your relationship with your father will improve.
