عَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ إِذَا نَزَلَ عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الْوَحْيُ يُسْمَعُ عِنْدَ وَجْهِهِ دَوِيٌّ كَدَوِيِّ النَّحْلِ
It is narrated from Sayyiduna Umar bin Khattab, may Allah be pleased with him, that when revelation would descend upon the Messenger of Allah, peace and blessings be upon him, a sound like the buzzing of bees could be heard near his blessed face.
