Musannaf Ibn Abi Shaybah 15324 — Selling the dwellings of Makkah

Alqamah bin Nadlah said: "In the time of the Prophet (peace and blessings be upon him), and in the time of Abu Bakr al-Siddiq and Umar, the houses of Makkah were called al-Sawa'ib (free, unowned): whoever was in need lived in them himself, and whoever was well off let others live in them."
