Hadith 3997
Narrated Ibn `Abbas: Abu Sa`id bin Malik Al-Khudri returned from a journey and his family offered him some meat of sacrifices offered at `Id ul Adha. On that he said, "I will not eat it before asking (whether it is allowed)." He went to his maternal brother, Qatada bin N i 'man, who was one of the Badr warriors, and asked him about it. Qatada said, "After your departure, an order was issued by the Prophet cancelling the prohibition of eating sacrifices after three days."
Hadith 5014
Narrated Abu Said Al-Khudri: My brother, Qatada bin An-Nau'man said, "A man performed the night prayer late at night in the lifetime of the Prophet and he read: 'Say: He is Allah, (the) One,' (112.1) and read nothing besides that. The next morning a man went to the Prophet ,~ and told him about that . (The Prophet replied the same as (in Hadith 532) above.)
Hadith 7374
Narrated Abu Sa`id Al-Khudri: A man heard another man reciting (in the prayers): 'Say (O Muhammad): "He is Allah, the One." (112.1) And he recited it repeatedly. When it was morning, he went to the Prophet and informed him about that as if he considered that the recitation of that Sura by itself was not enough. Allah's Apostle said, "By Him in Whose Hand my life is, it is equal to one-third of the Qur'an."
