7-5 Ahmad ibn Ziyad ibn Ja’far al-Hamadani - may God be pleased with him - narrated that Ali ibn Ibrahim ibn Hashem quoted on the authority of Muhammad ibn Al-Hassan al-Madani, on the authority of Abi Abdullah ibn Al-Fadhl, on the authority of his father Al-Fadhl:I was the gate-keeper for (Harun) Ar-Rashid. One day Harun was swinging around a sword and was very angry. He told me, “O Fadhl! I swear by my relationship with the Messenger of God (s) that if you do not bring my cousin here right away I will chop your head off.” I asked, “Who should I bring here?” He said, “This man from Hijaz.” I said, “Which man from Hijaz?” He said, “Musa ibn Ja’far Muhammad ibn Aliibn Al-Hussein ibn Ali ibn Abi Talib (s).”Al-Fadhl narrated, “I feared the Honorable the Exalted God to take Musa ibn Ja’far (s) to him. But I thought about the punishment I was threatened with and said, “I will do it.” Harun said, “Bring two men with whips, two with swords and two executioners.”Al-Fadhl narrated, “I prepared what he had ordered and went to the house of Abi Ibrahim Musa ibn Ja’far (s). I reached some ruins. There was a small room made with palm branches and leaves. A young black man was standing there. I told him, “Grant me permission to see your Master - may God have Mercy upon you!” He told me, “Go in. He does not have any gate-keepers or door men.” Then I went in to see him. I saw another black man who was cutting the callous that had formed on his forehead due to extensive prostrations. Then I said, “O son of the Prophet of God! Peace be upon you. Ar-Rashid has called you in.” He (s) said, “What does Ar-Rashid have to do with me? Has his pleasures not made him forget about me?” Then he (s) quickly got up and said, “Had I not heard the tradition in which God’s Prophet (s) has said, It is incumbent to obey the kings due to the principle of the concealment of faith.” I would never come with you.”I told him, “O Aba Ibrahim! May God have Mercy on you. Be prepared for his punishment.” He (s) said, “Is not the One who is the owner of this world and the Hereafter with me? The Sublime God willing, he cannot hurt me today.” Fadhl ibn Rabee’ said, “Then I saw that he (s) moved his hand over his head and turned it around thrice.”We went to see Ar-Rashid. He was standing while he was astonished like a woman who has lost her child. When he saw me he said, “O Fadhl!” I said, “Yes; sir!” He asked, “Did you bring my cousin?” I said, “Yes.” He said, “You did not upset him, did you?” I said, “No.” He said, “You did not tell me that I am angry with him, did you? I was too excited and did what I did not want to do. Let him in.” I let in the Imam (s). As soon as Harun saw the Imam (s), he rushed to him, hugged him and said, “Welcome! My cousin, my brother and the inheritor of my blessings.”Then he had him seated and asked, “How come you have stopped visiting us?” He (s) replied, “The extent of your reign and your love of this world.” Then Harun ordered that they bring a bottle of perfume. He put some perfume on the Imam (s) with his own hands. Then he orderedthem to bring several robes of honor and two bags of gold coins to be put in front of the Imam (s). Then Musa ibn Ja’far (s) said, “By God! If it was not the case that I can marry off the unmarried men from the progeny of Abi Talib so that their generation does not terminate, I would have not accepted this donation.”He (s) returned home while repeatedly saying, “Praise be to God - the Lord of the Two Worlds.” Fadhl said, “O Commander of the Faithful! You were determined to punish him, but you gave him robes of honor and honored him?” He said, “O Fadhl! When you left, I saw men who encircled my house. They were holding bayonets in their hands which they stuck into the ground at the base of the walls of the house and said, “If he bothers the son of the Messenger of God, we will destroy him and his house, but if he treats him kindly we will leave him alone and go.”Then I followed him (s) and asked him, “What did you say which helped you get relieved from Ar-Rashid?” He (s) said, “That is the supplications of my grandfather Ali ibn Abi Talib (s). Whenever he (s) recited it, he (s) defeated any army which he (s) faced, and defeated any fighter he (s) encountered. It is a supplication which brings immunity from calamities.” I asked him, “What is that supplication?”He said, “You must say, “O my Lord! I attack by relying on you. I seek what I want by relying on you. I talk relying on you. I succeed by relying on you. I die by your will, and I will be revived by your will. I submit myself to you, and entrust my affairs to you. And there is no power nor any strength save in the Sublime the Great God. O my Lord! You created me. You fed me and clothed me. You made me one of your self-sufficient servants by your own generosity. You return me to my original position whenever I fail. You strengthen me whenever I get weak. You heal me whenever I get ill. You answer me whenever I call you. O my Master! You have pleased me. Please be pleased with me.”
