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

Surah Al-Imran : 144
Muhammad is not but a messenger. [Other] messengers have passed on before him. So if he was to die or be killed, would you turn back on your heels [to unbelief]? And he who turns back on his heels will never harm Allah at all; but Allah will reward the grateful.
