وَمَا مُحَمَّدٌ إِلَّا رَسُولٌ قَدْ خَلَتْ مِن قَبْلِهِ الرُّسُلُ ۚ أَفَإِن مَّاتَ أَوْ قُتِلَ انقَلَبْتُمْ عَلَىٰ أَعْقَابِكُمْ ۚ وَمَن يَنقَلِبْ عَلَىٰ عَقِبَيْهِ فَلَن يَضُرَّ اللَّهَ شَيْئًا ۗ وَسَيَجْزِي اللَّهُ الشَّاكِرِينَ (144)
(3:144) Muhammad is no more than a Messenger, and Messengers have passed away before him. If, then, he were to die or be slain will you turn about on your heels? *103 Whoever turns about on his heels can in no way harm Allah. As for the grateful ones, Allah will soon reward them.
*103). When the rumour of the Prophet's martyrdom spread during the battle, it disheartened most of the Companions. The hypocrites who were in the Muslim camp began to advise the believers to approach 'Abd Allah b. Ubayy so that he might secure protection for them from Abu Sufyan. Some went so far as to say that had Muhammad really been the Messenger of God he would not have been put to death, and for that reason they counselled people to revert to their ancestral faith. It is in this context that the Muslims are now told that if their devotion to the truth is wholly bound up with the person of Muhammad (peace be on him), and if their submission to God is so lukewarm that his demise would cause them to plunge back into the disbelief they had cast off, then they should bear in mind the fact that Islam does not need them.
