Mukhtasar Bukhari (Abridged) 1080 — Sharecropping for half

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings of Allah be upon him) did not prohibit this (sharecropping), rather he (peace be upon him) said: "If any one of you gives (his land) to his brother free of charge, it is better than taking some rent for it."
