Sulaiman bin Abdul Malik narrated from a man that Amir al-Mu'minin Umar bin Abdul Aziz, may Allah have mercy on him, sent him a message and said: How is that hadith which you narrated to me from Sanasaji? He said, he informed me that he came to Amr bin Abasah, may Allah be pleased with him, and said, Is there any narration from the Messenger of Allah, peace and blessings be upon him, without any addition or omission? So he said, Yes, I heard the Messenger of Allah, peace and blessings be upon him, say: "Whoever frees a slave, Allah Almighty will free all his limbs from Hell in exchange for every limb (joint) of that slave, and whoever shoots an arrow in the way of Allah, whether it reaches the enemy or not, it is equal to freeing a slave, and whoever turns his hair white in the way of Allah, it will be light (illumination) for him on the Day of Resurrection."
