How can a person have strong Iman (Faith), apply the commands of Allah and fear His punishment?
This can be attained by reciting the Book of Allah, studying it, contemplating its meanings and rulings, studying the Sunnah (whatever is reported from the Prophet), knowing the details of Shari`ah (Islamic law) and acting upon them, and applying `Aqidah (creed) with all its deeds and sayings. A Muslim can also have strong Iman by sensing the greatness of Allah, being aware of His Oversight, and remembering the Last Day and the Day of Reckoning along with the reward, punishment, hardship, and terror that will take place on it. Moreover, a Muslim should accompany righteous people and avoid those who are evil and corrupt.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
