When Muhammad ﷺ saw Angel Jibreel

‘Abdullah ibn Mas‘ood said: 

“the Messenger of Allah ﷺ

saw Jibreel in his true form. He had six hundred wings, each of which covered the horizon. There fell from his wings jewels, pearls and rubies, only Allah knows about them.“

 Ahmad in al-Musnad, Ibn Katheer in al-Bidayah  isnad (chain of narrators) is jayyid (good).
