al-Ḥashr

فَكَانَ عَاقِبَتَهُمَا أَنَّهُمَا فِي النَّارِ خَالِدَيْنِ فِيهَا ۚ وَذَٰلِكَ جَزَاءُ الظَّالِمِينَ

The blessed Verse clearly expresses the fate of Satan and his followers as well as hypocrites and their disbelieving allies which is abiding in the Fire for ever. The general rule is that cooperation with disbelievers, hypocrites, Satan, and his allies entails defeat, misfortune, and torment in this world and the Hereafter; whereas, the cooperation of the believers and their allies is permanent and everlasting and it will entail triumph and being granted Divine Mercy in both worlds.
