Surah 48. Al-Fath

25Here, Allah in clear words is declaring all such people disbelievers and devoid of the faith, who are not sincere with regard to Allah and His Religion, who shirk endangering their interests, their lives and wealth for the sake of Allah's Religion when the time comes of their trial and test. But one should remember that this is not the .sort of disbelief on the basis of which somebody in the world may be regarded as excommunicated from Islam, but this is the disbelief because of which he will be declared a disbeliever in the Hereafter. The reason is that the Holy Prophet even after the revelation of this verse did not regard as outside Islam those people in respect of whom it was sent down, nor treated them like the disbelievers.

26The mention of Allah's being All-Forgiving and All-Merciful after the foregoing warning, contains in it a subtle aspect of admonition. It means this: 'Even now if you give up your insincere attitude and way of life and adopt sincerity, you will find Allah All- Forgiving and All-Merciful. He will forgive you your previous shortcomings and will treat you according to the quality of your sincerity in the future."
