قُلْ إِنِّى عَلَىٰ بَيِّنَةٍۢ مِّن رَّبِّى وَكَذَّبْتُم بِهِۦ ۚ مَا عِندِى مَا تَسْتَعْجِلُونَ بِهِۦٓ ۚ إِنِ ٱلْحُكْمُ إِلَّا لِلَّهِ ۖ يَقُصُّ ٱلْحَقَّ ۖ وَهُوَ خَيْرُ ٱلْفَٰصِلِينَ
Say: I am (relying) on clear proof from my Lord, while ye deny Him. I have not that for which ye are impatient. The decision is for Allah only. He telleth the truth and He is the Best of Deciders.
