يَتَوَٰرَىٰ مِنَ ٱلْقَوْمِ مِن سُوٓءِ مَا بُشِّرَ بِهِۦٓ ۚ أَيُمْسِكُهُۥ عَلَىٰ هُونٍ أَمْ يَدُسُّهُۥ فِى ٱلتُّرَابِ ۗ أَلَا سَآءَ مَا يَحْكُمُونَ
He hideth himself from the folk because of the evil of that whereof he hath had tidings, (asking himself): Shall he keep it in contempt, or bury it beneath the dust. Verily evil is their judgment.
