quran:53:18 –

He certainly saw of the greatest signs of his Lord.  

Verily he saw, in it, some of the greatest signs of his Lord, ˹some of˺ the most awesome ˹of these signs˺. He thus saw from among the marvels of the Realm (malakūt) a green drape (rafraf) that obscured the ˹entire˺ horizon of the heaven and Gabriel with his six hundred wings.
القرآن:٥٣:١٨ –

لَقَدْ رَأَىٰ مِنْ آيَاتِ رَبِّهِ الْكُبْرَىٰ  

{لقد رأى} فيها {من آيات ربه الكبرى} العظام، أي بعضها فرأى من عجائب الملكوت رفرفا أخضر سد أفق السماء وجبريل له ستمائة جناح.
