Mu'jam Kabir Tabarani 2662 — I came to the Messenger of Allah ﷺ during

The father of Ali bin Ali al-Hilali (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him) during the illness in which he passed away, and saw that Sayyidah Fatimah (may Allah be pleased with her) was at his head. She began to weep until her voice rose, so the Messenger of Allah (peace and blessings be upon him) raised his gaze towards her and said: "My beloved Fatimah, what makes you weep?" She said: I fear being left helpless after you. He (peace and blessings be upon him) said: "O my dear daughter, do you not know that Allah, the Mighty and Majestic, looked upon the earth and chose from it your father and sent him with His message, then He looked again and chose from it your husband, and revealed to me that I should marry you to him? O Fatimah, we are a household to whom Allah has given seven qualities that were not given to anyone before us and will not be given to anyone after us: I am the Seal of the Prophets, the most honoured of the prophets before Allah, and the most beloved of creation to Allah, the Mighty and Majestic, and I am your father; my executor (wasi) is the best of executors and the most beloved of them to Allah, and he is your husband; our martyr is the best of martyrs and the most beloved of them to Allah, and he is your uncle Hamzah bin Abd al-Muttalib, who is the uncle of your father and the uncle of your husband; and from us is one who has two green wings with which he flies in Paradise with the angels wherever he wishes, and he is the cousin of your father and the brother of your husband; and from us are the two grandsons of this Ummah, and they are your two sons Hasan and Husayn, and they are the leaders of the youth of Paradise, and their father - by the One who sent me with the truth - is better than them both. O Fatimah, by the One who sent me with the truth, from these two will be the Mahdi of this Ummah, when the world is in turmoil and chaos, trials become manifest, roads are cut off, and people raid one another, so that no elder shows mercy to a younger one and no younger one honours an elder. At that time Allah, the Mighty and Majestic, will raise from these two one who will open the fortresses of misguidance and sealed hearts; he will establish the religion at the end of time just as I established it at the beginning of time, and he will fill the world with justice just as it had been filled with oppression. O Fatimah, do not grieve and do not weep, for Allah, the Mighty and Majestic, is more merciful and more compassionate to you than I am, and that is because of your standing with me and your place in my heart. And Allah has married you to your husband, who is the noblest of your household in lineage, the most honoured in rank, the most merciful to the subjects, the most just in equal distribution, and the most discerning in judgement. And I have asked my Lord, the Mighty and Majestic, that you be the first of my household to join me." Sayyiduna Ali (may Allah be pleased with him) said: "When the Prophet (peace and blessings be upon him) passed away, Sayyidah Fatimah (may Allah be pleased with her) remained after him only seventy-five days until Allah joined her with him (peace and blessings be upon him)."
