Punishment of zina

Narrated Jabir bin `Abdullah Al-Ansari: A man from the tribe of Bani Aslam came to Allah's Apostle and Informed him that he had committed illegal intercourse and bore witness four times against himself. Allah's Apostle ordered him to be stoned to death as he was a married Person. Book: Sahih Bukhari, Chapter: Al-maharbeen, Hadees No. 6814 Narrated Ibn `Abbas: `Umar said, "I am afraid that after a long time has passed, people may say, "We do not find the Verses of the Rajam (stoning to death) in the Holy Book," and consequently they may go astray by leaving an obligation that Allah has revealed. Lo! I confirm that the penalty of Rajam be inflicted on him who commits illegal intercourse, if he is already married and the crime is proved by witnesses or pregnancy or confession." Sufyan added, "I have memorized this narration in this way." `Umar added, "Surely Allah's Apostle carried out the penalty of Rajam, and so did we after him." Book: Sahih Bukhari, Chapter: Al-maharbeen, Hadees No. 6829
