What sins will Allah not forgive?
Approved answer
Unforgivable Sin of Shirk
Shirk, which is the act of associating partners with Allah, is considered an unpardonable sin for those who pass away without having repented for it. Indeed, Allah does not forgive the act of worshiping others alongside Him; however, He may pardon any other sins for whom He wishes. Thus, anyone who commits shirk has undoubtedly committed a serious transgression.
