Dangers of Shirk
Shirk is the only unforgivable sin in the sight of Allah.
“Surely Allah does not forgive that anything should be associated with Him, and forgives what is besides that to whomsoever He pleases; and whoever associates anything with Allah has indeed devised a very great sin.” (An-Nisaa’, 4:48)
“Surely Allah does not forgive that anything should be associated with Him, and He forgives what is besides this to whom He pleases; and whoever associates anything with Allah has wandered far astray.”(An-Nisaa’, 4:116)
Shirk prohibits a person from entering Paradise, and obligates a permanent abode in Hell.
Surely whoever associates (others) with Allah, then Allah has forbidden Paradise for him, and his abode is Hell. (Al-Maa’idah, 5:72)
Shirk is so evil that it destroys all of a person’s good deeds.
“And certainly, it has been revealed to you and to those before you: Surely if you associate (withAllah), all your works will be nullified, and you will be with the losers.” (Az-Zumar:65)
If a person dies in a state of shirk, it is prohibited for his Muslim friends and relatives to seek forgiveness for him.
“It is not for the Prophet, and those who believe, to pray for the forgiveness of idolaters even though they may be near of kin (to them) after it has become clear that they are people of Hellfire.” (At-Tawbah, 9:113)
Allah has described those who commit shirk as being najas, or filthy.
“The idolaters are nothing but unclean.” (At-Tawbah, 9:28)
