وَمَا لَنَآ أَلَّا نَتَوَكَّلَ عَلَى ٱللَّهِ وَقَدْ هَدَىٰنَا سُبُلَنَا ۚ وَلَنَصْبِرَنَّ عَلَىٰ مَآ ءَاذَيْتُمُونَا ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُتَوَكِّلُونَ
How should we not put our trust in Allah when He hath shown us our ways? We surely will endure the hurt ye do us. In Allah let the trusting put their trust.
