Allah the most high says, “I created not the Jinn and humans except that they should worship Me (alone).”
[Surah adh-Dhariyaat(51):56]
Any type of worship mingles with even a mustard seed amount of shirk, all the worships unto Allah (All kinds of Ibadah) will be destroyed and invalidated. And whoever committed Shirk would be thrown to the Hell-fire eternally. So every Muslim should realize all the four principles of Shirk are the most important matter for him to learn.
“Verily Allah forgives not shirk (i.e., associating partners with Him in worship), but He forgives except that (anyone else) to whom He pleases.”[Surah an-Nisa(4):48]
Knowing Shirk comprises of knowing four principles that Allah has mentioned in His book.
Moreover , on the authority of Anas, who said: I heard the messenger of Allah say: Allah the almighty has said:”O son of Adam, so long as you call upon Me and ask Me, I shall forgive you for what you have done, and I shall not mind. O son of Adam, were your sins to reach the clouds of the sky and were you then to ask forgiveness of Me, I would forgive you. O son of Adam, were you to come to me with sins nearly as great as the earth and were you then to face Me, ascribing no partner to me, I would bring you forgiveness nearly as great as it’s.” related by Al-Tirmithi, who said that it was a good and sound Hadith.
