After this, it seems appropriate to mention a few incorrect beliefs, evil customs, and major sins which are committed quite often and which cause a shortcoming in one’s Imaan. In mentioning these things, it is hoped that people will guard themselves from them. Some of these are absolute kufr and shirk, some are very close to kufr and shirk, others are innovations and delusions, while others are sins. It is therefore necessary to safeguard one’s self from all of them. After mentioning these things, a few worldly harms of sinning and worldly benefits of good deeds will be mentioned. Since people tend to give more attention to worldly gains and losses, it is hoped that in this way there will be the desire to do good and abstain from evil.
