The Five Pillars of Islam are five basic acts in Islam, considered mandatory by believers and are the foundation of Muslim life.
Our Iman is not always as sound and strong as we want it to be as it often fluctuates according to life circumstances. There are several causes for weakening Iman such as deficiencies in our prayers or the insinuating whispers from the Shaytan. Regardless of the cause, it is crucial for all of us to keep a check on our Iman and if we feel it is faltering in any way then we should take measures to restore it. It is our responsibility to know which things decrease our Iman and how to avoid them and those that increase our Iman and how to embrace them.
Islam teaches the purest form of Monotheism and regards polytheism as the deadliest sin
Prophet Muhammad (Peace be upon him) said: "Is anyone of you incapable of earning one thousand Hasanah (rewards) a day?" Someone from the gathering asked, "How can anyone of us earn a thousand Hasanah?" Prophet Muhammad (Peace be upon him) said: "Glorify Allah a hundred times by just saying “Subhanallah” and a Good deeds will be written for you, or a thousand sins will be wiped away.” (Muslim 4:2073)
Increasing the Iman which Allah commands us to have, and which is a trait of His believing worshipers, can be achieved through different means
Causes of Increase in Iman
Faith is indeed a blessing from Allah and should not be taken for granted. Just as it may increase and become fuller and stronger, it may also weaken and become less and less until it is minimal or non-existent. Hence it becomes very important for a Muslim to take steps not only to preserve his faith but also to increase it.
we are born with the fitra or natural belief that our Lord is Only One Allah does not necessarily mean that the child will grow up to be what truly makes a person Muslim, which is ones iman
The Prophet Muhammad (S) said: "Faith wears out in the heart of any one of you just as clothes wear out, so ask Allah to renew the faith in your hearts” (Mustadrak al-Haakim).
