Restoring One's Iman

Indeed, the foremost concern of all the obligations upon the servant should be Īmān. It is the most valuable (thing) one can earn and obtain. With Īmān, one will achieve honor in this life and the one to come. In addition, all good that can be obtained in this life and the hereafter subjected to having sound Īmān

It is necessary for every servant who has Īmān and sincerity with himself to inspect his Īmān; does his Īmān grow, or does it wither?

The servant is in dire need to restore his Īmān, take steps in perfecting it, being on one's guard from things that decrease and weaken it, and make strides to strengthen it.

Īmān is subjected to afflictions by numerous matters that decrease it; among them are trials of this life, Shayṭān’s whispers, bad and corrupt companions, an evil soul that always calls to evil and so forth. So, one needs to take quick measures in strengthening and restoring it.

Al-Ḥākim reported in his book al-Mustadrak and at-Tabarānī reported in his book al-Mʿujam al-Kabīr on the authority of ʿAbdullāh bin ʿUmar bin al-Aas (radiyallahu 'anhu) said that the Messenger of Allāh (sallallahu' alayhi wa sallam) said,

"Indeed your faith wears out in your heart similar to how a Thawb wears out. So beg Allah to restore the faith in your hearts.
