Here is a comparison between two classes of the faithful. There are believers who are weak in will and prefer to sit down, or stay at home, and do the minor religious duties. Yet there are others who are resolute and determined to challenge with difficulties and gripple with obstacles. In the time of war, they fight bravely and are willing to sacrifice their lives and properties in the way of Allah. Although God's Mercy and goodness is promised to all the believers, but those who strive, are in the front line, and are accounted more glorious than those who sit down:

      ``Allah has promised all of them a good reward; but far greater is the reward of those who strive, and give to sacrifice their possession and self.''
