Hud - 11:12

فَلَعَلَّكَ تَارِكٌ بَعْضَ مَا يُوحَى إِلَيْكَ وَضَآئِقٌ بِهِ صَدْرُكَ أَن يَقُولُواْ لَوْلاَ أُنزِلَ عَلَيْهِ كَنزٌ أَوْ جَاء مَعَهُ مَلَكٌ إِنَّمَا أَنتَ نَذِيرٌ وَاللّهُ عَلَى كُلِّ شَيْءٍ وَكِيلٌ
[11:12]
Then, it may be that you will give up part of what is revealed to you and your breast will become straitened by it because they say: Why has not a treasure been sent down upon him or an angel come with him? You are only a warner; and Allah is custodian over all things.
Perchance thou mayest (feel the inclination) to give up a part of what is revealed unto thee, and thy heart feeleth straitened lest they say, "Why is not a treasure sent down unto him, or why does not an angel come down with him?" But thou art there only to warn! It is Allah that arrangeth all affairs!
A likely thing, that thou wouldst forsake aught of that which hath been revealed unto thee, and that thy breast should be straitened for it, because they say: Why hath not a treasure been sent down for him, or an angel come with him? Thou art but a warner, and Allah is in charge of all things.
