"Muhammd won in the short run, but in the long run the Umayyads slaughtered his descendants---"
>>> You are absolutely right!
Fatima died about 6months after the death of her father. He had lot of mental sufferings after Muhammd's death, inflicted by fellow Muslims. Within 10 days of the death of Muhammad, 'Fadak' was confiscated by 1st Caliph Abu Bakar from Fatima /Ali. Though Mohammad himself gifted it to his daughter. Muhammad owned it as "BOOTY" from the Jews of Khayber. Abu Bakr even did not give her chance to dry her "tears" after her father's death!
Ali did not get power till 656 CE, a long 24 yrs after the death of Muhammad! As soon as he got in power, the 1st civil war (Fitna) between Muslims started. He had the 1st war with Ayesha (mother in law). During his reign (656-661) he had the following wars:
- Battle of the Camel (between Ali and Ayesha) - December, 656 CE
- Battle of Siffin (between Ali and Muwabiya Ibne Abu Sufyan) – July, 657 C ( Kharijites break away from Ali)
- Battle of Nahrawan (Kharijites defeated by Ali) - 658 C
- Conquest of Egypt – 659 CE
Ali was brutally murdered (by a poisonous dragger) by one of the Kharijii on Januarry 661 CE. His elder son Hasan was brutally murdered by poison (conspiracy of Muawiya Ibne Abu Sufian) in 670 CE. His 2nd son Hussian Ibne Ali was brutally murdred by soldiers of Yazid bin Muawiya bin Abu Sufian in the battle of Karbala on October 680 CE.
Within 48 years of death of Prophet Muhammad, all of his able adult male immediate family members were brutally killed by fellow Muslims.
