So is it a lie Muhammad had never traveled to Jerusalem on the back of a woman, having the body of a horse?

Muhammad had never traveled to Jerusalem on the back of a woman, having the body of a horse; that he never ascended to the seventh heaven corporeally and that he made up the story of a mysterious journey to fool his Companions on the question they had raised on his whereabouts during the night he was spending in the company of his cousin, Umm Hani. This was the greatest lie ever spoken by a man; without it, Islam would have died its natural death a long, long time ago. And without Islam, the earth would have remained much better a place for all humans to live together in peace and harmony.
