Fatima was born on the 20th of Jamadiul Akhir, when the Prophet (pbuh) was 45 years old. She resided in Mecca for 8 years, and in Medina for 10 years. She lived for 75 days after the death of the Prophet (pbuh). She died on the 3rd of Jamadi al Thani, 11 AH. The cause of her death was that Qunfuz, the slave of Umar, struck her with the handle of his sword as per Umar’s order, which caused the miscarriage of her unborn son Muhsin and she became extremely sick. She did not allow anyone from her oppressors to approach her. The two men (who had oppressed her) were from the companions of the Prophet (pbuh). They requested Ali (as) to intercede to Fatima for them. Ali (as) asked her and she replied (granting them permission to talk to her). So when they approached her, they (audaciously) asked her: “How are you, O daughter of the Prophet (pbuh)?” She replied: “I am fine, by the grace of Allah (swt).” Then she confronted them: “Had you both not heard the Prophet (pbuh) say: Fatima is a part of me, whoever hurts her hurts me, and whoever hurts me has displeased/angered Allah”? They said: “Of course we had heard that.” She said: “So by Allah you both have hurt me!” Imam (as) said: “They both left her while she was furious at them.” Dalailul Imamah by Shaikh Tabari, Page 134
