مَّا أَصَابَكَ مِنْ حَسَنَةٍ فَمِنَ اللّهِWhatever of good reaches you, is from Allah,meaning, of Allah's bounty, favor, kindness and mercy.وَمَا أَصَابَكَ مِن سَيِّيَةٍ فَمِن نَّفْسِكَBut whatever of evil befalls you, is from yourself,meaning because of you and due to your actions. Similarly, Allah said,وَمَأ أَصَـبَكُمْ مِّن مُّصِيبَةٍ فَبِمَا كَسَبَتْ أَيْدِيكُمْ وَيَعْفُواْ عَن كَثِيرٍAnd whatever of misfortune befalls you, it is because of what your hands have earned. And He pardons much. (42:30) As-Suddi, Al-Hasan Al-Basri, Ibn Jurayj and Ibn Zayd said that, فَمِن نَّفْسِكَ (from yourself) means,because of your errors.Qatadah said that, فَمِن نَّفْسِكَ (From yourself) means,as punishment for you, O son of Adam, because of your sins.Allah said,وَأَرْسَلْنَاكَ لِلنَّاسِ رَسُولاًAnd We have sent you as a Messenger to mankind,so that you convey to them Allah's commandments, what He likes and is pleased with, and what He dislikes and refuses.وَكَفَى بِاللّهِ شَهِيدًاand Allah is sufficient as a Witness.that He has sent you. He is also Witness over you and them, having full knowledge in what you convey to them and the disbelief and rebellion with which they respond to the truth
