﴿ وَمَا مُحَمَّدٌ إِلَّا رَسُولٌۭ قَدْ خَلَتْ مِن قَبْلِهِ ٱلرُّسُلُ ۚ أَفَإِي۟ن مَّاتَ أَوْ قُتِلَ ٱنقَلَبْتُمْ عَلَىٰٓ أَعْقَٰبِكُمْ ۚ وَمَن يَنقَلِبْ عَلَىٰ عَقِبَيْهِ فَلَن يَضُرَّ ٱللَّهَ شَيْـًۭٔا ۗ وَسَيَجْزِى ٱللَّهُ ٱلشَّٰكِرِينَ ﴾

“AND MUHAMMAD is only an apostle; all the [other] apostles have passed away before him: if, then, he dies or is slain, will you turn about on your heels? But he that turns about on his heels can in no wise harm God - whereas God will requite all who are grateful [to Him].”
