﴿ وَمَا مَنَعَهُمْ أَن تُقْبَلَ مِنْهُمْ نَفَقَٰتُهُمْ إِلَّآ أَنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَبِرَسُولِهِۦ وَلَا يَأْتُونَ ٱلصَّلَوٰةَ إِلَّا وَهُمْ كُسَالَىٰ وَلَا يُنفِقُونَ إِلَّا وَهُمْ كَٰرِهُونَ ﴾

“For, only this prevents their spending from being accepted from them: they are bent on refusing to acknowledge God and His Apostle, and never pray without reluctance, and never spend [on righteous causes] without resentment.”

In Madinah the majority of all the people who had embraced Islam, were sincere believers. However, there were a number of people who had embraced Islam to go with the tide of the times, but who lacked that spirit of surrender which is the characteristic of true faith in and true attachment to God. These are the people who are known as hypocrites. These hypocrites consisted mostly of the wealthy class. It was this wealth which was behind their hypocrisy. Those who do not have anything to lose are ready and willing to accept that Islam in which one has to lose one’s all. But those who have something to lose generally become anxious about their worldly considerations. They somehow carry out those commandments of Islam which do not involve any sacrifice, but they find themselves unable to go ahead and accept any requirements of Islam which might involve loss of life and property, or when the question of becoming a believer at the level of sacrifice arises. But lagging behind in accepting the Islam of sacrifice renders even their prayers and fasting valueless. The rite of prayer (‘ibadah)—the worship performed in mosques—is intimately related with worship outside the mosque. If the individual’s life outside the mosque is devoid of the real spirit of religion, his life inside the mosque will also be empty of the true religious spirit and, obviously, action without such spirit has no value before God. God accepts nothing but righteous action. All else is devoid of merit in His eyes.
