Surat Luqman (Luqman) - لقمان

وَمَن يُسْلِمْ وَجْهَهُۥٓ إِلَى ٱللَّهِ وَهُوَ مُحْسِنٌ فَقَدِ ٱسْتَمْسَكَ بِٱلْعُرْوَةِ ٱلْوُثْقَىٰ وَإِلَى ٱللَّهِ عَٰقِبَةُ ٱلْأُمُورِ ﴿٢٢﴾

And whoever submits himself wholly to Allah and he is the doer of good (to others), he indeed has taken hold of the firmest thing upon which one can lay hold; and Allah's is the end of affairs.
