Narrated Al-Sa'ib bin Yazid: I was standing in the mosque and somebody threw a gravel at me. I looked and found that he was `Umar bin Al-Khattab. He said to me, "Fetch those two men to me." When I did, he said to them, "Who are you? (Or) where do you come from?" They replied, "We are from Ta'if." `Umar said, "Were you from this city (Medina) I would have punished you for raising your voices in the mosque of Allah's Apostle."

Narrated `Ata' bin Yasar: I asked Zaid bin Thabit about prostration on which he said that he had recited An-Najm before the Prophet, yet he (the Prophet) had not performed a prostration.

Narrated As-Sa'ib bin Yazid: Abu Sufyan bin Abu Zuhair, a man from Azd Shanu'a and one of the companions of the Prophet said, "I heard Allah's Apostle saying, 'If one keeps a dog which is meant for guarding neither a farm nor cattle, one Qirat of the reward of his good deeds is deducted daily." I said, "Did you hear this from Allah's Apostle?" He said, "Yes, by the Lord of this Mosque."

Narrated Sufyan bin Abi Zuhair Ash-Shani: That he heard Allah's Apostle saying, "If somebody keeps a dog that is neither used for farm work nor for guarding the livestock, he will lose one Qirat (of the reward) of his good deeds everyday."

Narrated Abu Sa`id Al-Khudri: While I was present in one of the gatherings of the Ansar, Abu Musa came as if he was scared, and said, "I asked permission to enter upon `Umar three times, but I was not given the permission, so I returned." (When `Umar came to know about it) he said to Abu Musa, "Why did you not enter?'. Abu Musa replied, "I asked permission three times, and I was not given it, so I returned, for Allah's Apostle said, "If anyone of you asks the permission to enter thrice, and the permission is not given, then he should return.' " `Umar said, "By Allah! We will ask Abu Musa to bring witnesses for it." (Abu Musa went to a gathering of the Ansar and said). "Did anyone of you hear this from the Prophet ?" Ubai bin Ka`b said, "By Allah, none will go with you but the youngest of the people (as a witness)." (Abu Sa`id) was the youngest of them, so I went with Abu Musa and informed `Umar that the Prophet had said so. (See Hadith No. 277, Vol. 3)

Narrated As-Sa'ib bin Yazid: We used to strike the drunks with our hands, shoes, clothes (by twisting it into the shape of lashes) during the lifetime of the Prophet, Abu Bakr and the early part of `Umar's caliphate. But during the last period of `Umar's caliphate, he used to give the drunk forty lashes; and when drunks became mischievous and disobedient, he used to scourge them eighty lashes.
