سورة آل عمران

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 ﴿١٤٤﴾

Surah Aali 'Imran

144. Muhammad is no more than a messenger. Messengers have passed before him. If he dies or gets killed, will you turn on your heels? He who turns on his heels will not harm Allah in any way. And Allah will reward the appreciative.
