It was narrated that Ibn shihab said:"I read the letter of the Messenger of allah which he wrote for 'Amr bin Hazm when he sent him to govern Najran. The letter was with Abu Bakr bin Hazm. The Messenger of Allah wrote this; 'A statement from Allah and His Messenger; O you who believe! Fulfill (your) obligations, and he wrote the Verses until he reached. Verily, Allah is Swift in reckoning. Then he wrote: 'this is the book if retaliation: For a soul, one hundred camels, '''' and so on
