It was related to me from Malik from Musa ibn Uqba from Abd ar- Rahman ibn Yazid al-Ansari that when Anas ibn Malik came back from Iraq, Abu Talha and Ubayy ibn Kab visited him. He brought them some cooked food and they ate, and then Anas got up and did wudu. Abu Talha and Ubayy ibn Kab asked, "What's this, Anas? Is it an Iraqi custom?" and Anas said, "I wish I had not done it." (i.e. wudu). Abu Talha and Ubayy ibn Kab both got up and prayed without doing wudu.

Ibn 'Abbas has reported this hadith on the authority of Ubayy b. ka'b that Allah's Apostle (may peace be upon him) used to recite this.

I asked Ubai bin Ka`b regarding the two Muwwidhat (Surats of taking refuge with Allah). He said, "I asked the Prophet about them, He said, 'These two Surats have been recited to me and I have recited them (and are present in the Qur'an).' So, we say as Allah's Apostle said (i.e., they are part of the Qur'an."

Allah's Apostle said, "Some poetry contains wisdom."

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."

Yahya related to me from Malik from Yahya ibn Said from Abdullah ibn Kab, the mawla of Uthman ibn Affan that Mahmud ibn Labid al-Ansari asked Zayd ibn Thabit about a man who penetrated his wife but became listless and did not ejaculate. Zayd ibn Thabit said, "He does ghusl." Mahmud said to him, "Ubayy ibn Kab used not to think that ghusl was necessary," but Zayd ibn Thabit said, "Ubayy ibn Kab drew away from that before he died."

`Abdullah bin `Amr mentioned `Abdullah bin Masud and said, "I shall ever love that man, for I heard the Prophet saying, 'Take (learn) the Qur'an from four: `Abdullah bin Masud, Salim, Mu`adh and Ubai bin Ka`b.' "

Once while I was with the Prophet and Sa`d, Ubai bin Ka`b and Mu`adh were also sitting with him, there came to him a messenger from one of his daughters, telling him that her child was on the verge of death. The Prophet told the messenger to tell her, "It is for Allah what He takes, and it is for Allah what He gives, and everything has its fixed time (limit). So (she should) be patient and look for Allah's reward."

Ubayy b. Ka'b reported that he was sitting in a mosque that a person entered it and he observed prayer, and made recitation, the rest of the hadith is the same.

I asked Allah's Apostle about a man who engages in sexual intercourse with his wife but does not discharge. He replied, "He should wash the parts which comes in contact with the private parts of the woman, perform ablution and then pray." (Abu `Abdullah said, "Taking a bath is safer and is the last order.")

Jabir reported that Allah's Messenger (may peace be upon him) sent a phystian to Ubayy b. Ka'b. He cut the vein and then cauterised it.

I asked Anas bin Malik: "Who collected the Qur'an at the time of the Prophet ?" He replied, "Four, all of whom were from the Ansar: Ubai bin Ka`b, Mu`adh bin Jabal, Zaid bin Thabit and Abu Zaid."

I was serving Abu 'Ubaida, Abu Talha and Ubai bin Ka`b with a drink prepared from ripe and unripe dates. Then somebody came to them and said, "Alcoholic drinks have been prohibited." (On hearing that) Abu Talha said, "Get up. O Anas, and pour (throw) it out! So I poured (threw) it out.

That he heard Allah's Apostle saying, "(The prophet) Moses said to his attendant, "Bring us our early meal' (18.62). The latter said, 'Did you remember when we betook ourselves to the rock? I indeed forgot the fish and none but Satan made me forget to remember it." (18.63) Moses did not feel tired till he had crossed the place which Allah ordered him to go to."

Allah's Apostle neither talked in an insulting manner nor did he ever speak evil intentionally. He used to say, "The most beloved to me amongst you is the one who has the best character and manners." He added, " Learn the Qur'an from (any of these) four persons. `Abdullah bin Mas`ud, Salim the freed slave of Abu Hudhaifa, Ubai bin Ka`b, and Mu`adh bin Jabal."

`Abdullah bin Masud was mentioned before `Abdullah bin `Amr who said, "That is a man I still love, as I heard the Prophet saying 'Learn the recitation of Qur'an from four from `Abdullah bin Mas`ud -- he started with him--Salim, the freed slave of Abu Hudaifa, Mu`adh bin Jabal and Ubai bin Ka`b."

I asked Ubai bin Ka`b, "O Abu AlMundhir! Your brother, Ibn Mas`ud said so-and-so (i.e., the two Mu'awwidh-at do not belong to the Qur'an)." Ubai said, "I asked Allah's Apostle about them, and he said, 'They have been revealed to me, and I have recited them (as a part of the Qur'an)," So Ubai added, "So we say as Allah's Apostle has said."

`Abdullah (bin Mas`ud) was mentioned before `Abdullah bin `Amr. The latter said, "That is a man I continue to love because I heard Allah's Apostle saying, ' Learn the recitation of the Qur'an from (any of these) four persons: `Abdullah bin Masud, Salim the freed slave of Abu Hudhaifa, Ubai bin Ka`b, and Mu`adh bin Jabal." I do not remember whether he mentioned Ubai first or Mu`adh.

I asked `Uthman bin `Affan about a person who engaged in intercourse but did no discharge. `Uthman replied, "He should perform ablution like the one for an ordinary prayer but he must wash his penis." `Uthman added, "I heard it from Allah's Apostle." I asked `Ali Az-Zubair, Talha and Ubai bin Ka`b about it and they, too, gave the same reply. (This order was canceled later on and taking a bath became necessary for such cases).

I used to offer drinks prepared from infused dates to Abu Talha Al-Ansari, Abu 'Ubada bin Al Jarrah and Ubai bin Ka`b. Then a person came to them and said, "All alcoholic drinks have been prohibited." Abii Talha then said, "O Anas! Get up and break all these jars." So I got up and took a mortar belonging to us, and hit the jars with its lower part till they broke.

Anas said When the verse “You will never attain righteousness until you give freely of what you love" came down, Abu Talhah said Messenger of Allah (saws), I think our Lord asks us for our property. I call you as witness that I dedicate my land at Ariha ‘to Him’. The Messenger of Allah (saws) said to him Divide it among your nearest relatives. So he divided it among Hassan bin Thabit and Ubayy bin Ka’b.

Abu Dawud said I have been gold by an Ansari Muhammad bin ‘Abdallah that the name of Abu Talhah is Zaid bin Sahal bin al-Aswad bin Haram bin ‘Amar bin Zaid bin Manat bin ‘Adi bin ‘Amr bin Malik bin al-Najjar; and Hassan bin Tabit is son of al-Mundhir in al-Haram. Thus both of them (Abu Talhah and Hassan) have their common link in Haram who is the third great grandfather. Ubbay bin Ka’b is son of Qais bin ‘Atik bin Zaid bin Mu’awiyah bin ‘Amr bin Malik bin al-Najjar. Thus the common tie between Hassan, Abu Talhah and Ubbay is ‘Amr (bin Malik). The Ansari said between Ubbay and Abi Talhah there are six great grandfathers.
