﴿ 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!"”

Kill Joseph or cast him away into some land that is into some distant land so that your father might be solely concerned with you so that he might turn his attention to you and not be distracted by anyone else and that thereafter that is after killing Joseph or casting him away you might be a righteous folk’ by repenting.
