It is narrated from Sayyiduna Abu Layla (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "No servant truly believes until I am dearer to him than his own self, and my family is dearer to him than his own family, and my person is dearer to him than his own person."
