Sahih al-Bukhari Book 78, Hadith 36
The Prophet (ﷺ) said, "I and the person who looks after an orphan and provides for him, will be in
Paradise like this," putting his index and middle fingers together.
I never felt so jealous of any woman as I did of Khadija, though she had died three years before the Prophet married me, and that was because I heard him mentioning her too often, and because his Lord had ordered him to give her the glad tidings that she would have a palace in Paradise, made of Qasab and because he used to slaughter a sheep and distribute its meat among her friends.
The Prophet (ﷺ) said "The one who looks after and works for a widow and for a poor person, is like a warrior fighting for Allah's Cause or like a person who fasts during the day and prays all the night." Narrated Abu Huraira that the Prophet (ﷺ) said as above.
