The Holy Quran 6:147 — Surah Al-An'am
Arabic text
فَإِن كَذَّبُوكَ فَقُل رَّبُّكُمْ ذُو رَحْمَةٍ وَٰسِعَةٍ وَلَا يُرَدُّ بَأْسُهُۥ عَنِ ٱلْقَوْمِ ٱلْمُجْرِمِينَ
Translation
So if they reject you (O Muhammad ﷺ and speak lies about the message you gave them), then tell them that your Rabb is the possessor of all-embracing mercy (His punishment will therefore not strike immediately and He is always prepared to forgive) and (if you choose not to accept Imaan, then remember that) His punishment will not be turned away from the sinful people.
Tafsir (excerpt) — Tafsir Usmani
that is, you have been spared until now by the breadth of mercy; do not think that the punishment has been averted. So it is in Mudih al-Quran.
