قَالُوا أَوَلَمْ تَكُ تَأْتِيكُمْ رُسُلُكُم بِالْبَيِّنَاتِ ۖ قَالُوا بَلَىٰ ۚ قَالُوا فَادْعُوا ۗ وَمَا دُعَاءُ الْكَافِرِينَ إِلَّا فِي ضَلَالٍ (50)
(40:50) The keepers of Hell will ask: 'Did your Messengers not come to you with Clear Signs?' They will say: 'Yes (they did).' The keepers of Hell will say: 'Then you yourselves should call (upon the Lord). And the call of the unbelievers will end in vain.' *66
*66) That is, 'When the fact is this that the Messengers had come to you with the clear Signs, and you have already been sentenced to suffer punishment here, because you had refused to believe in them, it is not possible for us to pray for you to Allah. For obviously there should be some plea for such a prayer, and you have exhausted every plea by your misconduct. So, you pray for yourselves if you so like: but we would tell you beforehand that the prayers of the people who had disbelieved in the world like you have been of no avail.
