Sahih al-Bukhari, Volume 4, Book 55, Hadith 640 (USC-MSA) ⓘ

Narrated Malik bin Sasaa: That the Prophet talked to them about the night of his Ascension to the Heavens. He said, "(Then Gabriel took me) and ascended up till he reached the second heaven where he asked for the gate to be opened, but it was asked, 'Who is it?' Gabriel replied, 'I am Gabriel.' It was asked, 'Who is accompanying you?' He replied, 'Muhammad.' It was asked, 'Has he been called?' He said, 'Yes.' When we reached over the second heaven, I saw Yahya (i.e. John) and Jesus who were cousins. Gabriel said, 'These are John (Yahya) and Jesus, so greet them.' I greeted them and they returned the greeting saying, 'Welcome, O Pious Brother and Pious Prophet!;' "
