Fadak

Fadak is a Jewish oasis in the north of the Hijaz, near Khaybar. On the Prophet's return from Khaybar, its people made a settlement with him to give up half the land and its produce, so the pure half became a share of the Prophet's, which he spent on wayfarers. ¹

Its people remained there until Umar ibn al-Khattab, in his caliphate, expelled them to Syria, along with the Jews of Khaybar, after valuing their share of the palms and land at a fair price. ¹

In Sahih al-Bukhari, within Umar's account of the Prophet's properties, he says that Fadak was for wayfarers. ²
