The Qur’an is a very complete guide for human life for daily needs, especially the problem of being firm in the heart in faith, so as not to slip into the slander that is very much at the end of this era. In the Qur’an there are many verses related to the firmness of the heart in faith. The word abât in the Qur’an is repeated 18 times in 11 surahs with various derivations. Then from these many verses the author only takes the abât verses that are related to the issue of being firm in faith. The results of this study note that the concept of abât in Ibn Kaṡîr’s perspective has eight forms, namely in the form of orders, prohibitions, praise, reproaches, suggestions and motivations, threats, stories, and examples. Several factors so that a person can be said to have had the nature of abât including being sincere because of Allah Ta’âlâ, doing good deeds, being aware of the blessings of Allah Ta’âlâ, praying, reading and practicing the contents of the Qur’an, contemplating the signs the power of Allah, help Allah Ta’âlâ, and listen to the stories of the previous pious people.
