The Holy Quran 7:72 — Surah Al-A'raf
Arabic text
فَأَنجَيْنَـٰهُ وَٱلَّذِينَ مَعَهُۥ بِرَحْمَةٍ مِّنَّا وَقَطَعْنَا دَابِرَ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَـٰتِنَا ۖ وَمَا كَانُوا۟ مُؤْمِنِينَ
Translation
So (when Allaah's punishment came in the form of a severe windstorm that lasted for 7 nights and eight days) We saved him and those who were with him by Our mercy and We cut off the roots of (completely destroyed) those who rejected Our Aayaat and who did not have Imaan.
Tafsir (excerpt) — Tafsir Usmani
