وَيَوْمَ يَقُولُ نَادُوا۟ شُرَكَآءِىَ ٱلَّذِينَ زَعَمْتُمْ فَدَعَوْهُمْ فَلَمْ يَسْتَجِيبُوا۟ لَهُمْ وَجَعَلْنَا بَيْنَهُم مَّوْبِقًۭا
And (be mindful of) the Day when He will say: Call those partners of Mine whom ye pretended. Then they will cry unto them, but they will not hear their prayer, and We shall set a gulf of doom between them.
Surah Al-Kahf(18:52)
