Narrated by Sayyiduna Malik bin Harith (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever includes an orphan, who has lost both parents, in his own food and drink until that orphan becomes independent, then Paradise is absolutely obligatory for such a person. And whoever frees a Muslim slave, it will be a cause for his freedom from Hell; every limb of that slave will suffice for every limb of the one who freed him from the Fire.
