Quran 4:79 An-Nisa, ayah 79 of 176

مَّآ أَصَابَكَ مِنْ حَسَنَةٍ فَمِنَ ٱللَّهِ ۖ وَمَآ أَصَابَكَ مِن سَيِّئَةٍ فَمِن نَّفْسِكَ ۚ وَأَرْسَلْنَـٰكَ لِلنَّاسِ رَسُولًا ۚ وَكَفَىٰ بِٱللَّهِ شَهِيدًا ۝٧٩

4:79 Whatever of good befalleth thee (O man) it is from Allah, and whatever of ill befalleth thee it is from thyself. We have sent thee (Muhammad) as a messenger unto mankind and Allah is sufficient as Witness.
