Whoever recites it (i.e., the invocation in the above Hadith (412) ten times will be as if he manumitted one of Ishmael's descendants. Abu Aiyub narrated the same Hadith from the Prophet saying, "(Whoever recites it ten times) will be as if he had manumitted one of Ishmael's descendants."

While Allah's Apostle was prostrating (as stated below).

Narrated `Abdullah bin Mas`ud:

Once the Prophet was offering prayers at the Ka`ba. Abu Jahl was sitting with some of his companions. One of them said to the others, "Who amongst you will bring the Abdominal contents (intestines, etc.) of a camel of Bani so and so and put it on the back of Muhammad, when he prostrates?" The most unfortunate of them got up and brought it. He waited till the Prophet prostrated and then placed it on his back between his shoulders. I was watching but could not do any thing. I wish I had some people with me to hold out against them. They started laughing and falling on one another. Allah's Apostle was in prostration and he did not lift his head up till Fatima (Prophet's daughter) came and threw that (camel's Abdominal contents) away from his back. He raised his head and said thrice, "O Allah! Punish Quraish." So it was hard for Abu Jahl and his companions when the Prophet invoked Allah against them as they had a conviction that the prayers and invocations were accepted in this city (Mecca). The Prophet said, "O Allah! Punish Abu Jahl, `Utba bin Rabi`a, Shaiba bin Rabi`a, Al-Walid bin `Utba, Umaiya bin Khalaf, and `Uqba bin Al Mu'it [??] (and he mentioned the seventh whose name I cannot recall). By Allah in Whose Hands my life is, I saw the dead bodies of those persons who were counted by Allah's Apostle in the Qalib (one of the wells) of Badr.

Sa`d bin Mu`adh came to Mecca with the intention of performing `Umra, and stayed at the house of Umaiya bin Khalaf Abi Safwan, for Umaiya himself used to stay at Sa`d's house when he passed by Medina on his way to Sham. Umaiya said to Sa`d, "Will you wait till midday when the people are (at their homes), then you may go and perform the Tawaf round the Ka`ba?" So, while Sa`d was going around the Ka`ba, Abu Jahl came and asked, "Who is that who is performing Tawaf?" Sa`d replied, "I am Sa`d." Abu Jahl said, "Are you circumambulating the Ka`ba safely although you have given refuge to Muhammad and his companions?" Sa`d said, "Yes," and they started quarreling. Umaiya said to Sa`d, "Don't shout at Abi-l-Hakam (i.e. Abu Jahl), for he is chief of the valley (of Mecca)." Sa`d then said (to Abu Jahl). 'By Allah, if you prevent me from performing the Tawaf of the Ka`ba, I will spoil your trade with Sham." Umaiya kept on saying to Sa`d, "Don't raise your voice." and kept on taking hold of him. Sa`d became furious and said, (to Umaiya), "Be away from me, for I have heard Muhammad saying that he will kill you." Umaiiya said, "Will he kill me?" Sa`d said, "Yes,." Umaiya said, "By Allah! When Muhammad says a thing, he never tells a lie." Umaiya went to his wife and said to her, "Do you know what my brother from Yathrib (i.e. Medina) has said to me?" She said, "What has he said?" He said, "He claims that he has heard Muhammad claiming that he will kill me." She said, By Allah! Muhammad never tells a lie." So when the infidels started to proceed for Badr (Battle) and declared war (against the Muslims), his wife said to him, "Don't you remember what your brother from Yathrib told you?" Umaiya decided not to go but Abu Jahl said to him, "You are from the nobles of the valley (of Mecca), so you should accompany us for a day or two." He went with them and thus Allah got him killed.

From Sa`d bin Mu`adh: Sa`d bin Mu`adh was an intimate friend of Umaiya bin Khalaf and whenever Umaiya passed through Medina, he used to stay with Sa`d, and whenever Sa`d went to Mecca, he used to stay with Umaiya. When Allah's Apostle arrived at Medina, Sa`d went to perform `Umra and stayed at Umaiya's home in Mecca. He said to Umaiya, "Tell me of a time when (the Mosque) is empty so that I may be able to perform Tawaf around the Ka`ba." So Umaiya went with him about midday. Abu Jahl met them and said, "O Abu Safwan! Who is this man accompanying you?" He said, "He is Sa`d." Abu Jahl addressed Sa`d saying, "I see you wandering about safely in Mecca inspite of the fact that you have given shelter to the people who have changed their religion (i.e. became Muslims) and have claimed that you will help them and support them. By Allah, if you were not in the company of Abu Safwan, you would not be able to go your family safely." Sa`d, raising his voice, said to him, "By Allah, if you should stop me from doing this (i.e. performing Tawaf) I would certainly prevent you from something which is more valuable for you, that is, your passage through Medina." On this, Umaiya said to him, "O Sa`d do not raise your voice before Abu-l-Hakam, the chief of the people of the Valley (of Mecca)." Sa`d said, "O Umaiya, stop that! By Allah, I have heard Allah's Apostle predicting that the Muslim will kill you." Umaiya asked, "In Mecca?" Sa`d said, "I do not know." Umaiya was greatly scared by that news. When Umaiya returned to his family, he said to his wife, "O Um Safwan! Don't you know what Sa`d told me? "She said, "What has he told you?" He replied, "He claims that Muhammad has informed them (i.e. companions that they will kill me. I asked him, 'In Mecca?' He replied, 'I do not know." Then Umaiya added, "By Allah, I will never go out of Mecca." But when the day of (the Ghazwa of) Badr came, Abu Jahl called the people to war, saying, "Go and protect your caravan." But Umaiya disliked to go out (of Mecca). Abu Jahl came to him and said, "O Abu Safwan! If the people see you staying behind though you are the chief of the people of the Valley, then they will remain behind with you." Abu Jahl kept on urging him to go until he (i.e. Umaiya) said, "As you have forced me to change my mind, by Allah, I will buy the best camel in Mecca. Then Umaiya said (to his wife). "O Um Safwan, prepare what I need (for the journey)." She said ...
