Verse 64

قَالَ هَلْ ءَامَنُكُمْ عَلَيْهِ إِلَّا كَمَآ أَمِنتُكُمْ عَلَىٰٓ أَخِيهِ مِن قَبْلُ فَٱللَّهُ خَيْرٌ حَـٰفِظًا وَهُوَ أَرْحَمُ ٱلرَّٰحِمِينَ

He said; how can I trust you with him, as I trusted you with his brother before? God is the best guardian and of all the merciful ones He is the most merciful.
