Fadak (Arabic: فدك) is a village in Hijaz, which had lush gardens with date palm trees which was conquered by Muslims after the Battle of Khaybar. The notability of Fadak is because of the quarrel between Lady Fatima (a) and Abu Bakr over its ownership, after the demise of Prophet (s). After Abu Bakr reached caliphate he confiscated Fadak which was gifted to Lady Fatima (a) by the Prophet (s). After Lady Fatima (a) gave evidence, Abu Bakr admitted that he was wrong and wrote a handwriting that no one should encroache on it. But Umar b. al-Khattab took the handwriting and tore it. In the Fadakiyya Sermon Lady Fatima (a) complained about this incident.
During the time of the Umayyads and the Abbasids this area was in the hands of the caliphs. Yet, some of these caliphs, including Umar b. 'Abd al-'Aziz and al-Ma'mun, returned it to the descendants of Lady Fatima (a), but the subsequent caliphs seized them. Today, Fadak is located in a city called al-Hait.
