Hence, preparation for that eventuality must start now and must continue in every moment of one s life. It is the combination of his need to prepare for the hereafter, to make sure that one s good deeds are weighty, and the natural human tendency to do what is good and to excel that Islam strengthens within every Muslim. Islam thus imparts its own colour to its followers, making of them men and women who are always prepared to do what is good and to sacrifice for it their time, wealth and comfort. Islam achieves all that very easily through a method which makes Muslims aware that when they do good they get the benefit of their deeds in their lives and they are rewarded for them in the hereafter. Thus they combine immediate worldly benefits with future divine reward.
Every human being has a natural tendency to be good.
Every one loves honesty, loyalty, truthfulness and all related virtues. When you add to this love the sense that by telling the truth you are not only doing your duty and observing moral values, but you are also earning reward in the hereafter, then the motivation to always tell the truth and to always refrain from telling lies is far stronger. The Prophet has emphasised this combination on every occasion. He has always tried to instil in his followers this double motivation to observe Islamic values which are indeed the highest of moral values. This statement by the Prophet has more or less become a proverb in the Arabic language.
