Clear Quran
Ali 'Imran · 3:144
وَمَا مُحَمَّدٌ إِلَّا رَسُولٌ قَدْ خَلَتْ مِنْ قَبْلِهِ الرُّسُلُ ۚ أَفَإِنْ مَاتَ أَوْ قُتِلَ انْقَلَبْتُمْ عَلَىٰ أَعْقَابِكُمْ ۚ وَمَنْ يَنْقَلِبْ عَلَىٰ عَقِبَيْهِ فَلَنْ يَضُرَّ اللَّهَ شَيْئًا ۗ وَسَيَجْزِي اللَّهُ الشَّاكِرِينَ
Muḥammad is no more than a messenger; other messengers have gone before him. If he were to die or to be killed, would you regress into disbelief? Those who do so will not harm Allah whatsoever. And Allah will reward those who are grateful.
