What Is Îmân?

Hadrat Imâm-i Rabbânî says in the 67th letter of the second volume of his Maktûbât: 

Îmân means to believe the teachings coming from our Prophet, which are written in the books of Ahl as-sunnat savants, and to express one's belief. Worships are not from îmân. But they perfect and beautify îmân. Imâm-i a'zâm Abû Hanîfa 'alaihirrahma' said that îmân does not increase or decrease. For, îmân means the heart's confirmation, admitting and believing.

There is not scarcity or abundance in îmân. Belief which has its decrease and increase is not called îmân, but it is called supposition and illusion. Îmân's being much or little means muchness or scarcity in worships. When a person worships much, he is said to have much perfection in his îmân.

Then, the îmâns of all Believers are unlike the îmâns of prophets. For, prophets' îmân has reached the summit of perfection on account of worships. The îmân of other Believers cannot reach there. But both have the common quality of being îmân. The former has become different through worships. It is as if there were no resemblance between them. All Believers and prophets share the property of being human. But other values, superiorities have made prophets reach high grades. Their humanity has become sort of different. In a way, they are higher human beings than the common humanity. Perhaps, they only are human beings. Others, as it were, are not human beings.
