قَالَ يَٰقَوْمِ أَرَءَيْتُمْ إِن كُنتُ عَلَىٰ بَيِّنَةٍۢ مِّن رَّبِّى وَرَزَقَنِى مِنْهُ رِزْقًا حَسَنًۭا ۚ وَمَآ أُرِيدُ أَنْ أُخَالِفَكُمْ إِلَىٰ مَآ أَنْهَىٰكُمْ عَنْهُ ۚ إِنْ أُرِيدُ إِلَّا ٱلْإِصْلَٰحَ مَا ٱسْتَطَعْتُ ۚ وَمَا تَوْفِيقِىٓ إِلَّا بِٱللَّهِ ۚ عَلَيْهِ تَوَكَّلْتُ وَإِلَيْهِ أُنِيبُ
He said: O my people! Bethink you: if I am (acting) on a clear proof from my Lord and He sustaineth me with fair sustenance from Him (how can I concede aught to you)? I desire not to do behind your backs that which I ask you not to do. I desire naught save reform so far as I am able. My welfare is only in Allah. In Him I trust and unto Him I turn (repentant).
