Ameer al-Mu'mineen Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Eat olive oil (by mixing it in your food) and apply it (to your body), for it is from a blessed tree (its fruit)." Abu Isa al-Tirmidhi (may Allah have mercy on him) says: In the chain of this hadith, the narrator 'Abdur Razzaq is inconsistent; sometimes he narrates it as musnad and sometimes as mursal.
