"Einstein wrote something in which he said he had converted to Islam and had become a Shiite Muslim and that he was a disciple of Imam Ja'far Sadeq, says so in foreign books. Einstein says 'when I heard about the ascension of the prophet Mohamad' where he had ascended to heavens and come back and the house door was still shaking, a process which was faster than the speed of light. The prophet went quicker than the light that walks, I don't know how much is it? 300,000 km per second! The door knocker was still shaking and the prophet had come back and he had seen all the heavens too. This is the very same relativity movement that Einstein had understood. Similar to what Mullah Sadra had understood before him, a quintessential movement, not a positional movement like crossing the road taking ten minutes, a movement of light or rather a spiritual movement faster than the light moves, Einstein said 'when I heard about the narratives of the prophet Mohamad and that of the Ahle-Beit [prophet's household] I realised they had understood these things way before us"
