23. Among the believers are men who have been true to their covenant with Allâh [i.e. they have gone out for Jihâd (holy fighting), and showed not their backs to the disbelievers]; of them some have fulfilled their obligations (i.e. have been martyred); and some of them are still waiting, but they have never changed [i.e. they never proved treacherous to their covenant which they concluded with Allâh] in the least.[1]
