The Prophet said that he and anyone who cares for an orphan by providing for their needs will be together in Paradise, likening their bond to being as close as two fingers pressed together.
2. Narrated Sahl bin Sa'd: The Prophet 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. (SahihBukhari, Vol. 8, Hadith # 34)
