إِن تَدْعُوهُمْ لَا يَسْمَعُوا۟ دُعَآءَكُمْ وَلَوْ سَمِعُوا۟ مَا ٱسْتَجَابُوا۟ لَكُمْ ۖ وَيَوْمَ ٱلْقِيَٰمَةِ يَكْفُرُونَ بِشِرْكِكُمْ ۚ وَلَا يُنَبِّئُكَ مِثْلُ خَبِيرٍۢ
If ye pray unto them they hear not your prayer, and if they heard they could not grant it you. On the Day of Resurrection they will disown association with you. None can inform you like Him Who is Aware.
