Anas (May Allah be pleased with him) reported in the course of his famous Hadith pertaining to Al-Isra' (the Ascension) that Messenger of Allah ﷺ said, "Then Jibril (Gabriel) ascended along with me to the nearest heaven and requested for the gate to be opened. He was asked:
`Who is there?' He replied: `Jibril.' He was asked: `Who is with you?' He said: `Muhammad.' Then he ascended to the second heaven and requested for the opening of the gate. He was asked: `Who is there?' He said: `Jibril.' He was asked: `Who is with you?' He replied: `Muhammad.' In the same way he ascended to the third, fourth and all the heavens (i.e., until the seventh). At all of the gates he was asked: `Who is there?' He replied: Jibril.'''

عن أنس رضي الله عنه في حديثه المشهور في الإسراء قال: قال رسول الله ﷺ : "ثم صعد بي جبريل إلي السماء الدنيا فاستفتح، فقيل: من هذا؟ قال: جبريل، قيل:ومن معك؟ قال: محمد. ثم صعد إلي السماء الثانية والثالثة والرابعة وسائرهن، ويقال في باب كل سماء: من هذا؟ فيقول: جبريل" ((متفق عليه)).
