<b>Yusuf comforts Binyamin</b> 

Allah tells:

وَلَمَّا دَخَلُواْ عَلَى يُوسُفَ اوَى إِلَيْهِ أَخَاهُ قَالَ إِنِّي أَنَاْ أَخُوكَ فَلَ تَبْتَيِسْ بِمَا كَانُواْ يَعْمَلُونَ
 
 

And when they went in before Yusuf, he took his brother (Binyamin) to himself and said:"Verily, I am your brother, so grieve not for what they used to do." 

Allah states that when Yusuf's brothers went in before him along with his full brother Binyamin, he invited them to a place of honor as privileged guests. He granted them gifts and generous hospitality and kindness. He met his brother in confidence and told him the story of what happened to him and that he was in fact his brother. He said to him, 
لَا تَبْتَيِسْ
 `(grieve not) nor feel sad for what they did to me.'

He ordered Binyamin to hide the news from them and to refrain from telling them that the Aziz is his brother Yusuf. He plotted with him to keep him in Egypt enjoying honor and great hospitality
