قُلْ يَٰٓأَيُّهَا ٱلنَّاسُ إِن كُنتُمْ فِى شَكٍّ مِّن دِينِى فَلَآ أَعْبُدُ ٱلَّذِينَ تَعْبُدُونَ مِن دُونِ ٱللَّهِ وَلَٰكِنْ أَعْبُدُ ٱللَّهَ ٱلَّذِى يَتَوَفَّىٰكُمْ ۖ وَأُمِرْتُ أَنْ أَكُونَ مِنَ ٱلْمُؤْمِنِينَ
109:3.
6:164.
Commentary:
The Holy Prophet is here made to say to disbelievers, "You say you have doubts concerning my religion, whereas my acting on this very religion has given me an invincible conviction of faith. I wonder why this religion should give rise to doubts in your minds?"
The expression, causes you to die, has been employed here to hint that the God of Islam was in the end going to punish disbelievers.
