Tafsir Ibn Kathir -> Surah Al-Mulk -> The Death of the Believer will not save the Disbeliever, so let Him reflect upon His Deliverance

Allah says,

﴿قُلْ﴾

(say) `O Muhammad to these idolators who are associating partners with Allah and denying His favors,'

﴿أَرَءَيْتُمْ إِنْ أَهْلَكَنِىَ اللَّهُ وَمَن مَّعِىَ أَوْ رَحِمَنَا فَمَن يُجِيرُ الْكَـفِرِينَ مِنْ عَذَابٍ أَلِيمٍ﴾

(Tell me! If Allah destroys me, and those with me, or He bestows His mercy on us - who can save the disbelievers from a painful torment) meaning, `save yourselves, for verily, there is nothing that can rescue you from Allah except repentance, turning to Him for forgiveness and returning to His religion. Your hopes that torment and exemplary punishment will strike us, will not benefit you. Whether Allah punishes us or has mercy on us, there is no escaping from Allah's punishment and painful torment that you will suffer.' Then Allah says,

﴿قُلْ هُوَ الرَّحْمَـنُ ءَامَنَّا بِهِ وَعَلَيْهِ تَوَكَّلْنَا﴾

(Say: "He is the Most Gracious, in Him we believe, and upon Him we rely.) meaning, `we believe in the Lord of all that exists, the Most Gracious, the Most Merciful, and upon Him we rely in all of our affairs.' This is as Allah says,

﴿فَاعْبُدْهُ وَتَوَكَّلْ عَلَيْهِ﴾

(So worship Him and rely upon Him.) (11:123) Thus, Allah continues saying,

﴿فَسَتَعْلَمُونَ مَنْ هُوَ فِى ضَلَـلٍ مُّبِينٍ﴾

(So, you will come to know who it is that is in manifest error.) meaning, `between Us and you, and to whom the final end (ultimate victory) will be for in this life and in the Hereafter.'
