فَإِن كَذَّبُوكَ فَقُل رَّبُّكُمۡ ذُو رَحۡمَةٖ وَٰسِعَةٖ وَلَا يُرَدُّ بَأۡسُهُۥ عَنِ ٱلۡقَوۡمِ ٱلۡمُجۡرِمِينَ ١٤٧
So if they deny you, [O Muḥammad], say, "Your Lord is the possessor of vast mercy; but His punishment cannot be repelled from the people who are criminals."
Translation: Saheeh International (English)
Each word's meaning and sound
If they deny you, O Messenger, and do not accept what you brought from your Lord, then say to them in encouragement: Your Lord is One, possessor of vast mercy. It is because of His mercy that He has given you relief and has not yet taken you to task by punishing you. Also say to them as a warning: His punishment is not averted from those who commit sins.
