5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn abu Najran from Hammad ibn ‘Uthman from al-Misma’I who has said that when Dawud ibn Ali killed al-Mu’alla’ ibn Khunays, Abu ‘Abdillah (a.s.) said the following: “Abu ‘Abd Allah (a.s.) said, ‘I will pray to Allah against whoever has murdered my Mawla (servant) and has seized my property.’ Dawud ibn Ali then said, ‘You threaten me with your prayer! (But I am not afraid).’ Hammad has said that al-Misma’i said that Mu’attib said to me, ‘Abu ‘Abd Allah (a.s.) that night continued his Ruku ’ and Sajdah and, when it was morning, I hear him saying in Sajdah (prostration) “O Lord, I ask You through Your power that is strong, through Your glory that is intense, that has humbled Your creatures, grant favors to Muhammad and his family and seize him (the enemy) in this hour! Seize him in this hour!’ He had not yet raised his head that we heard crying and wailing from the house of Dawud ibn Ali. Abu ‘Abd Allah (a.s.) raised his head and said, ‘I prayed to Allah with a prayer and Allah, the Most Majestic, the Most Holy, sent an angel over him to hit his head with an iron bar that ruptured his bladder and caused his death.’” Note: Dawud ibn Ali was the governor of Madinah during the rule of abu al- ‘Abbas al-Saffah. He ordered al-Mu’alla to identify for him every Shi’a (follower A ’ immah ) of abu ‘Abd Allah (a.s.). He refused saying, ‘Even if they were under my foot I would not raise it to expose them.’ He was murdered and the properties of Abu ‘Abdillah (a.s.) with him was seized.

1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Muhammad ibn Hakim from abu Masruq who has said the following: “Once I said to Abu ‘Abdillah (a.s.) ‘We speak to people and in support of our (Shi’a Muslim) belief refer them to the words of Allah, the Most Majestic, the Most Holy, ‘O believers, obey Allah, His Messenger, and your leaders (who possess Divine Authority)...’ (4:59) They say, ‘It applies to the commanders of the missions of armed forces.’ “We then refer them to the words of Allah, the Most Majestic, the Most Holy, ‘Only Allah, His Messenger, and the true believers who are steadfast in prayer and pay alms, while they kneel during prayer, are your guardians.’ (5:55) They say, ‘This applies to the believing people (as a whole).’ “We refer them to the words of Allah, the Most Majestic, the Most Holy, ‘(Muhammad), say, “I do not ask you for any payment for my preaching to you except (your) love of (my near) relatives...’” (42:23) They say, ‘It applies to the relatives of the Muslims.’ “I (the narrator) then mentioned all such references that I knew of and the Imam said, ‘If such is the case, call them for Al- Mubahalah (pleading before Allah for help against the enemy).’ I then asked, ‘How should I do that?’ The Imam said, ‘Correct your soul three days,’ I think he said, ‘Fast, take a shower and both of you go in the mountains, crisscross the fingers of your right hand with his fingers, then yield for justice against yourself (begin with yourself) and say, “O Lord, the Cherisher of the seven heavens and seven earths, the One who possesses the knowledge of the unseen and seen, the Beneficent, the Merciful, if abu Masruq has denied anyone’s rights or has claimed falsehood, send upon him misfortune from the sky or a painful punishment.” Then turn it to him and say, ‘If so and so has rejected a truth or made a false claim, send upon him a misfortune from the sky or a painful punishment.’ Then the Imam said to me, ‘You will very shortly see it in him.’ The narrator has said, ‘I swear by Allah I could not find any creature, who could accept my call for Al-Mubahalah (pleading before Allah for help against the enemy).”’
