It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that Sayyidah Umm Kulthum (may Allah be pleased with her) came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, the husband of Sayyidah Fatimah (may Allah be pleased with her) is better than my husband." The Messenger of Allah (peace and blessings be upon him) remained silent for a while, then said: "Your husband is one whom Allah and His Messenger love, and he loves Allah and His Messenger; and I will tell you something more: if you were to enter Paradise and see his station, you would not find anyone of my Companions above him in rank."
