It is narrated from Hazrat Malik bin Harith that he heard the Messenger of Allah say: Whoever includes an orphan child of Muslim parents in his food and drink until the child becomes independent of this help and starts earning himself, then Paradise is certainly made obligatory for him. Whoever frees a Muslim man becomes the cause of his freedom from Hell, and for every limb of the freed person, each of his own limbs is freed from Hell.
