it is noteworthy that some interesting incidents featured the muslims’ march towards khaibar; of which we mention the following:
the messenger of allâh [pbuh] said: "who is this driver (of the camels)?" they said: "it is ‘amir." he said: "allâh will show mercy to him." a man said: "martyrdom is reserved for him; o messenger of allâh, would that you had allowed us to benefit ourselves from his life."[sahih al-bukhari 2/603; sahih muslim 2/115] the prophet’s companions had already known that he would never invoke allâh’s mercy upon a close companion but to single him out for martyrdom.[sahih muslim 2/115]
