Al-Anbiya' - 21:109

فَإِن تَوَلَّوْا فَقُلْ آذَنتُكُمْ عَلَى سَوَاء وَإِنْ أَدْرِي أَقَرِيبٌ أَم بَعِيدٌ مَّا تُوعَدُونَ
[21:109]
But if they turn back, say: I have given you warning in fairness and I do not know whether what you are threatened with is near or far;
But if they turn back, Say: "I have proclaimed the Message to you all alike and in truth; but I know not whether that which ye are promised is near or far.
But if they are averse, then say: I have warned you all alike, although I know not whether nigh or far is that which ye are promised.
