Musannaf Ibn Abi Shaybah 39334 — Reports on the Miraj, when

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "On the night on which I was taken on the Night Journey, I saw that when we reached the seventh heaven, I raised my gaze above me, and I saw thunder, lightning and thunderbolts." He (peace and blessings be upon him) said: "I came to a people whose bellies were like houses, and in them were snakes that could be seen from the outside. I asked: 'O Jibril! Who are these people?' Jibril said: 'These are the consumers of usury (riba).' Then when I descended to the lowest heaven, I looked below, and I perceived dust, smoke and voices. I asked: 'O Jibril! What is this?' Jibril said: 'These are the devils, who deceive the eyes of the children of Adam. They do not reflect upon the signs of the heavens and the earth. Were it not for these things, the children of Adam would see wonders.'"
