Muslims are addressed here to perform one of their most important duties which may serve to unify their society, strengthen their government and defensive forces, and besides all, is an effective means of salvation in Dooms Day: ``O, Believers! Bestow in alms a part of what we have given you.'' The verse ends in a warning which may indicate that by alms; `ZAKAT' is meant here which is a duty incumbent upon Muslims. It also puts some stress upon the people to do it before they lose the chance of doing it: ``A day in which there is no trading, neither friendship and nor intercessor.''
