Umayr, freed slave of Ibn Abbas (may Allah be pleased with him), from Ibn Abbas (may Allah be pleased with him)

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: "Seven (relations) are forbidden on account of lineage, and seven are also forbidden on account of marriage ties." Then he recited this verse: "Forbidden to you are your mothers" [Surah al-Nisa: 23] until he reached "and the daughters of the sister" [Surah al-Nisa: 23], then said: "This is the prohibition by lineage." Then he recited this verse: "And your mothers who nursed you" [Surah al-Nisa: 23] until he reached "and that you combine two sisters together" [Surah al-Nisa: 23], then he recited this verse: "And do not marry those women whom your fathers married" [Surah al-Nisa: 22], then said: "This is the prohibition by marriage ties."

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: When the Messenger of Allah (peace and blessings be upon him) returned from Ta'if, he stayed at al-Ji'ranah and distributed the spoils of war there, then he performed Umrah from there, and that was when two nights of Shawwal remained.
