It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "I am a guarantor, for the one who gives up arguing even though he is in the right, of a house on the outskirts of Paradise, a house in the middle of Paradise and a house in the highest part of Paradise."
