We continued up into the second heaven. I saw two people who resembled one another. I asked, "Jibra'il, who are these two people?'
He replied, "They are Yahya and `Isa, two Prophets and cousins of one another." I greeted them both and prayed to Allah for this forgiveness. They both greeted me back and prayed for my forgiveness; and after welcoming me said: "Welcome O' Righteous and good brother of ours!" In that place, there were also Angels present who were prostrating with humbleness and humility. Allah the Almighty had created them in various forms, and in various voices they were busy in praising and glorifying Allah."
