Iman — this is the unshakeable faith in one, all-powerful Creator, about whose essence and existence it is ordained to us to learn from the revelations of His Prophet, may Allah bless his name.
There are two ways of believing. Some simply accept the faith, perceiving the vital need for it and its truth, and strengthen their belief by means of reasonable arguments. We call this yakini iman or true faith. Others believe by drawing wisdom from books and from the words of the mullah. Such people need special dedication to the object of their faith and spiritual strength in order to withstand thousands of temptations and not waver even in the face of death. This is the taklidi iman or traditional faith.
To keep iman within one's self, a person must have a courageous heart, firm will and confidence in his powers. But what about those who lack the knowledge to be among the adherents of yakini iman, or those who have no firm belief, who too easily succumb to temptations and cajolery who for gain will call black white, and white black, who will perjure themselves by passing off lies as truth and so cannot be called taklidi iman believers? May Allah preserve us from such people! Each and every one of us should remember that there can be no other iman save these. Let apostates not reckon on infinite divine grace; they deserve neither Allah's forgiveness nor the Prophet's intercession. Cursed be the man who believes in the false proverbs:
"The edge of the sword is sharper than an oath" and "There is no sin that Allah will not pardon".
