Causation in Islamic Theology

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

What comes to you of good is from Allāh, but what comes to you of evil, [O man], is from yourself. And We have sent you, [O Muḥammad], to the people as a messenger, and sufficient is Allāh as Witness.
