3:144
وَمَا مُحَمَّدٌ إِلَّا رَسُولࣱ قَدۡ خَلَتۡ مِن قَبۡلِهِ ٱلرُّسُلُۚ أَفَإِی۟ن مَّاتَ أَوۡ قُتِلَ ٱنقَلَبۡتُمۡ عَلَىٰۤ أَعۡقَـٰبِكُمۡۚ وَمَن یَنقَلِبۡ عَلَىٰ عَقِبَیۡهِ فَلَن یَضُرَّ ٱللَّهَ شَیۡـࣰٔاۗ وَسَیَجۡزِی ٱللَّهُ ٱلشَّـٰكِرِینَ
Muhammad is but a messenger, messengers (the like of whom) have passed away before him. Will it be that, when he dieth or is slain, ye will turn back on your heels? He who turneth back on his heels doth no hurt to Allah, and Allah will reward the thankful.
— Mohammed Marmaduke William Pickthall
