Sura al-Nisāʾ 4:79

مَّآ أَصَابَكَ مِنْ حَسَنَةٍ فَمِنَ ٱللَّـهِ وَمَآ أَصَابَكَ مِن سَيِّئَةٍ فَمِن نَّفْسِكَ وَأَرْسَلْنَٰكَ لِلنَّاسِ رَسُولًا وَكَفَىٰ بِٱللَّـهِ شَهِيدًا

mā aṣābaka min ḥasanatin fa-mina allāhi wa-mā aṣābaka min sayyiʾatin famin nnafsika wa-arsalnāka lil-nāsi rasūlan wa-kafā billāhi shahīdan

Whatever good, (O man!) happens to thee, is from Allah; but whatever evil happens to thee, is from thy (own) soul. and We have sent thee as a messenger to (instruct) mankind. And enough is Allah for a witness.
