Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated: The Prophet (peace and blessings be upon him) was commanded to prostrate on seven parts of the body, and not to gather the hair or clothes. Ibrahim bin Maisarah narrated: I asked Tawus (may Allah have mercy on him) about prostrating on the nose, and he said: It is better. Ishaq (may Allah have mercy on him) said: The forehead and the nose are the same thing.
