وَلَا يَحْزُنكَ ٱلَّذِينَ يُسَٰرِعُونَ فِى ٱلْكُفْرِ ۚ إِنَّهُمْ لَن يَضُرُّوا۟ ٱللَّهَ شَيْـًٔا ۗ يُرِيدُ ٱللَّهُ أَلَّا يَجْعَلَ لَهُمْ حَظًّا فِى ٱلْءَاخِرَةِ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌ
5:42.
Commentary:
The clause, who hastily fall into disbelief, refers to the hypocrites and the weak in faith whom the slightest trial throws into disbelief. The word "portion" means "portion of grace and God’s mercy".
5:42.
Those who try to harm Islam or the Holy Prophet and his followers, in reality, try to harm God Himself, because the cause of the Holy Prophet is God’s own cause.
