It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever honours my sanctity regarding my Companions will come to me at my Basin, and whoever does not honour my sanctity regarding my Companions will see me on the Day of Resurrection only from afar."
