Surat Yusuf (8-9)

{إِذْ قَالُواْ لَيُوسُفُ وَأَخُوهُ أَحَبُّ إِلَى أَبِينَا مِنَّا وَنَحْنُ عُصْبَةٌ إِنَّ أَبَانَا لَفِي ضَلاَلٍ مُّبِينٍ} (يوسف : 8 )

8- Some of Yusuf's brothers said to one another: By Allah, Yusuf and his brother are more beloved to our father than we are —Yusuf and his brother were from a different mother— and as a group we can do things better then both of them. There is no doubt our father is mistaken in his inclination to them, why does he love two boys more than a strong group like us?

{اقْتُلُواْ يُوسُفَ أَوِ اطْرَحُوهُ أَرْضاً يَخْلُ لَكُمْ وَجْهُ أَبِيكُمْ وَتَكُونُواْ مِن بَعْدِهِ قَوْماً صَالِحِينَ} (يوسف : 9 )

9- Some of them said after Satan had decorated evil and seduced them: Kill Yusuf who seized the love of your father or cast him in a remote land to get rid of him and enjoy the love of your father, then you repent of your sins and become pious.
