How to increase Iman
Sheikh Ibn ‘Uzaimin (may Allah have mercy on him):
“Many people call us [and complain]:” I do not find [the real] iman in me, “” I did not touch the iman of my heart, “” I do not find its sweetness, “etc.
The way out of this situation is as follows:
– Turn [all the time] to Allah,
– increase dhikr,
– increase [voluntary] prayers,
– increase your reading of the Quran,
increase good deeds and various kinds of good deeds to your brothers / sisters [by faith] – you will find this sweetness. “
