Wa maa Muhammadun illaa Rasoolun qad khalat min qablihir Rusul; afa'im maata aw qutilan qalabtum 'alaaa a'qaabikum; wa mai yanqalib 'alaa aqibihi falai yadurral laaha shai'aa; wa sayajzil laahush shaakireen
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.
