The prescribed punishment for false accusation of adultery, and the warning about it

Sayyiduna Hudhayfah (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "Falsely accusing a chaste woman of fornication demolishes the deeds of a hundred years."
Al-Tabarani and al-Bazzar recorded it; its chain contains Layth bin Abi Sulaym, who is da'if (weak), though his hadith is sometimes graded hasan (good); the rest of its narrators are the narrators of the Sahih.

Sayyiduna Abu al-Yusr (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said to Sayyidah Aishah (may Allah be pleased with her): "O Aishah! Indeed, Allah Almighty has sent down a ruling about your innocence." Sayyidah Aishah (may Allah be pleased with her) said: "I praise Allah Almighty; I do not praise you." The Prophet (peace and blessings be upon him) went out from Sayyidah Aishah (may Allah be pleased with her); he sent for Abdullah bin Ubayy and gave him the punishment of two prescribed punishments. Then he sent for a man named Mistah and a woman named Hamnah, and had them beaten as well.
Al-Tabarani recorded it; its chain contains Isma'il bin Yahya al-Taymi, who is a liar (kadhdhab).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) had them given eighty (80) lashes each.
Al-Tabarani recorded it; its chain contains Muhammad bin al-Sa'ib al-Kalbi, who is a liar (kadhdhab). In the chapter on the virtues of Sayyidah Aishah (may Allah be pleased with her) a hadith from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) will come, in which it is mentioned that they will be flogged on the Day of Resurrection as well.

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) decreed regarding the child of a husband and wife who have undertaken li'an (mutual imprecation) that the child will inherit from his mother and his mother will inherit from him; whoever accuses that woman of fornication will be given eighty lashes, and whoever calls her son one born of fornication will also be given eighty lashes.
Ahmad recorded it by way of Ibn Ishaq, and stated that Amr bin Shu'ayb mentioned it. If there is an explicit statement of hearing in this, then its narrators are thiqat (trustworthy); otherwise it is a narration by 'an'anah (using "from") of Ibn Ishaq, and he is a mudallis; the rest of its narrators are thiqat (trustworthy).

Al-Qasim narrates: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "There is a prescribed punishment in one of two cases only: that you accuse a chaste woman of fornication, or that you deny a man's lineage from his father."
Al-Tabarani recorded it; the narrator al-Qasim did not hear from his grandfather Sayyiduna Abdullah (may Allah be pleased with him), though its narrators are thiqat (trustworthy).

Abu Uthman al-Nahdi narrates: Sayyiduna Abu Bakrah (may Allah be pleased with him), Sayyiduna Nafi' (may Allah be pleased with him) and Sayyiduna Shibl bin Ma'bad (may Allah be pleased with him) testified against Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) that they had seen him, and seen him in the way a kohl stick is inserted into a kohl container. Then Ziyad came, and Sayyiduna Umar (may Allah be pleased with him) said: "A man has come who will testify only according to the truth." He said: "I saw a scene that was ugly and blameworthy." The narrator says: So Sayyiduna Umar (may Allah be pleased with him) had those men flogged as the prescribed punishment.
Al-Tabarani recorded it, and its narrators are the narrators of the Sahih.
