Tafsir

Shirk is the Worst form of Wrong, its Practitioner shall never succeed. Allah threatens those who associate anything else with

Him and worship anything with Him. He informs that those whoassociate others with Allah:لاَ بُرْهَانَ لَهُ(of whom he has no proof), meaning no evidence for what he says. Then Allah says:وَمَن يَدْعُ مَعَ اللَّهِ إِلَـهَا ءَاخَرَ لاَ بُرْهَانَ لَهُ بِهِ(And whoever invokes, besides Allah, any other god, of whom he has no proof;) this is a conditional sentence, whose fulfilling clause is:فَإِنَّمَا حِسَابُهُ عِندَ رَبِّهِ(then his reckoning is only with his Lord.) meaning, Allah will call him to account for that. Then Allah tells us:إِنَّهُ لاَ يُفْلِحُ الْكَـفِرُونَ(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.وَقُل رَّبِّ اغْفِرْ وَارْحَمْ وَأنتَ خَيْرُ الرَحِمِينَ (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.
