Surah Al-Mu'minun 23:117

Shirk is the Worst form of Wrong, its Practitioner shall never succeed. Allah threatens those who associate anything else withHim and worship anything with Him. He informs that those whoassociate others with Allah:

(of whom he has no proof), meaning no evidence for what he says. Then Allah says:

(And whoever invokes, besides Allah, any other god, of whom he has no proof;) this is a conditional sentence, whose fulfilling clause is:

(then his reckoning is only with his Lord.) meaning, Allah will call him to account for that. Then Allah tells us:

(Surely, disbelievers will not be successful.) meaning, they will not be successful with Him on the Day of Resurrection; they will not prosper or be saved.

(And say: "My Lord! Forgive and have mercy, for You are the best of those who show mercy!") Here Allah is teaching us to recite this supplication, for forgiveness, in a general sense, means wiping away sins and concealing them from people, and mercy means guiding a person and helping him to say and do good things.

Ayat ini menerangkan bahwa orang-orang yang menyembah Allah dan menyekutukan-Nya dengan tuhan yang lain, padahal tidak ada yang pantas disembah melainkan Allah, pada hakikatnya tidak ada alasan sama sekali yang dapat membenarkan perbuatan mereka itu. Mereka akan diajukan ke hadapan Allah, untuk memperhitungkan dan mempertanggung-jawabkan segala perbuatan mereka. Allah yang akan menyempurnakan ganjaran atas perbuatan mereka. Sesungguhnya orang-orang kafir itu tidak akan beruntung selama-lamanya, dan tidak akan luput dari azab yang menyiksanya.
