Musnad Abu Ya'la al-Mawsili 110:130

Wahb ibn Baqiyyah narrated to us, Khalid narrated to us, Husayn narrated to us, from Ikrimah, from Ibn Abbas, that the Prophet (peace and blessings of Allah be upon him) said: "Whoever takes an orphan from among the Muslims into his food and drink until Allah makes him self-sufficient, Allah will certainly make Paradise obligatory for him, unless he commits a sin that is not forgiven. And whoever supports three daughters, spends on them, and treats them well, Paradise becomes obligatory for him." A man from the Bedouins stood up and said, "Or two?" He said, "Yes." Even if he had said one, he would have said yes. "And there is no servant whose two precious things Allah takes away, except that his reward with Allah is Paradise." He asked, "And what are his two precious things?" He said, "His two eyes." And Ibn Abbas, when he would narrate this hadith, would say, "By Allah, this is among the precious and most excellent of hadiths."
