The Messenger of Allah (saws) as saying: The atonement for a vow is the same as for an oath.

Abu Dawud said: This tradition has also been transmitted by 'Amr b. al-Harith from Ka'b b. 'Alqamah, from Ibn Shamasah on the authority of 'Uqbah.

Al-Hasan reported: Umar ibn al-Khattab gathered the people (in tarawih prayer) behind Ubayy ibn Ka'b (who led them). He used to lead them for twenty days (during Ramadan, and would not recite the supplication except in the second half of it (i.e. Ramadan). When the last ten days remained, he kept away from them, and prayed in his house. They used to say: Ubayy ran away.

Abu Dawud said: This tradition shows that whatever has been reported about the recitation of the supplication is not tenable. Moreover, these two traditions from Ubayy b. Ka'b indicate that another tradition which tells that the Prophet (saws) recited the supplication in the witr is weak.

The Messenger of Allah (saws) used to say at the end of his witr: "O Allah, I seek refuge in Thy good pleasure from Thy anger, and in Thy forgiveness from Thy punishment, and I seek refuge in Thy mercy from Thy wrath. I cannot reckon the praise due to Thee. Thou art as Thou hast praised Thyself."

Abu Dawud said: Hisham is the earliest teacher of Hammad. Yahya b. Ma'in said: No one is reported to have narrated traditions form him except Hammad b. Salamah.

Abu Dawud said: Ubayy b. Ka'b said: The Messenger of Allah (saws) recited supplication in the witr before bowing.

Abu Dawud said: This tradition has also been narrated by 'Isa b. Yunus through a different chain of narrators from Ubayy b. Ka'b. He also narrated it through a different chain of narrators on the authority of Ubayy b. Ka'b that the Messenger of Allah (saw) recited the supplication in the witr before bowing.

Abu Dawud said: The chain of narrators of the tradition of Sa'id from Qatadah goes: Yazid b. Zurai' narrated from Sa'id, from Qatadah, from 'Azrah, from Sa'id b. 'Abd al-Rahman b. Abza, on the authority of his father, from the Prophet (saws). This version does not mention the supplication and the name of Ubayy. This tradition has also been narrated by 'Abd al-A'la and Muhammad b. Bishr al-'Abdi. He heard the traditions from 'Isa b. Yunus at Kufah. They did not mention the supplication in their version.

This tradition has also been narrated by Hisham al-Dastuwa'i and Shu'bah from Qatadah. They did not mention the supplication in their version. The tradition of Zubaid has been narrated by Sulaiman al-A'mash, Shu'bah, 'Abd al-Malik b. Abi Sulaiman, and Jarir b. Hazim; all of them narrated on the authority of Zubaid. None of them mention the supplication in his version, except in the tradition transmitted by Hafs b. Ghiyath from Mis'ar from Zubaid; he narrated in his version that he (the Prophet) recited supplication before bowing.

Abu Dawud said: This version of tradition is not well know. There is doubt that Hafs might have narrated this tradition from some other narrator than Mis'ar.

Abu Dawud said: It is reported that Ubayy (b. Ka'b) used to recited the supplication )in the witr) in the second half of Ramadan.

This hadith has been narrated by Husain with the same chain of transmitters, but no mention is made of Umm Ka'b.

The Messenger of Allah (saws) once prayed wearing a garment having marks. He looked at its marks. When he saluted, he said: Take this garment of mine to AbuJahm, for it turned my attention just now in my prayer, and bring a simple garment without marks.

Abu Dawud said: The name of Abu Jahm b. Hudhaifah from Banu 'Adi b. Ka'b b. Ghanam

This hadith has been narrated on the authority of Ibn Ka'b through another chain of transmitters but with " "the similitude of the disbeliever is that of a cypress tree".

When the Prophet (saws) intended to go on an expedition, he always pretended to be going somewhere else, and he would say: War is deception.

Abu Dawud said: Only Ma'mar has transmitted this tradition. By this he refers to his statement "War is deception" through this chain of narrators. He narrated it from the tradition of 'Amr b. Dinar from Jabir, and from the tradition of Ma'mar from Hammam b. Munabbih on the authority of Abu Hurairah.

The Messenger of Allah (saws) came out and saw that the people were praying during (the night of) Ramadan in the corner of the mosque. He asked: Who are these people ? It was said to him that those were people who had not learnt Quran. But Ubayy b. Ka'b is praying and they would pray behind him. The Prophet (saws) said: They did right and it is good what they did.

Abu Dawud said: This tradition is not strong, the narrator Muslim b. Khalid is weak.

The Messenger of Allah (saws) as saying: No one withholds goods till their price rises but a sinner. I said to Sa'id (b. al-Musayyab): You withhold goods till their price rises. He said: Ma'mar used to withhold goods till their price rose.

Abu Dawud said: I asked Ahmad (b. Hanbal): What is hoarding (hukrah) ? He replied: That on which people live.

Abu Dawud said: Al-Auza'i said: A muhtakir (one who hoards) is one who withholds supply of goods in the market.

that he heard Allah's Apostle saying, "(Moses) said, 'Call me not to account for what I forget and be not hard upon me for my affair (with you)' (18.73) the first excuse of Moses was his forgetfulness."

Abu Dawud said: This tradition has been narrated by Yunus from Ibn Shihab from some of the children of al-Sa'ib son of Abu Lubabah. A similar tradition has also been transmitted by al-Zabidi from al-Zuhri from Husain b. al-Sa'ib son of Abu Lubabah.

On the authority of his father: Umm Mubashshir said to the Prophet (saws) during the sickness of which he died: What do you think about your illness, Messenger of Allah (saws)? I do not think about the illness of my son except the poisoned sheep of which he had eaten with you at Khaybar. The Prophet (saws) said: And I do not think about my illness except that. This is the time when it cut off my aorta.

Abu Dawud said: Sometime 'Abd al-Razzaq transmitted this tradition, omitting the link of the Companion, from Ma'mar, from al-Zuhri, from the Prophet (saws), and sometimes he transmitted it from al-Zuhri from 'Abd al-Rahman b. Ka'b b. Malik, 'Abd al-Rahman mentioned that Ma'mar sometimes transmitted the tradition in a mursal form (omitting the link of the Companion), and they recorded it. And all this is correct with us. 'Abd al-Razzaq said: When Ibn al-Mubarak came to Ma'mar, he transmitted the traditions in a musnad form (with a perfect chain) which he transmitted as mauquf traditions (statements of the Companions and not of the Prophet).
