It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him), describing to them the events of the night of the Ascension, said: "Jibril and I ascended to the lowest heaven, and there I met an angel called Isma'il; he is the one in charge of the lowest heaven. Before him were seventy thousand angels, and with each angel was his army of one hundred thousand angels." And he (peace and blessings be upon him) recited this verse: "And none knows the armies of your Lord except Him."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Rashid al-Himmani except Abd al-Wahhab al-Khaffaf."
