Sahih Bukhari | Volume 6 | Hadith Number 97
Narrated by 'Aisha
There was an orphan (girl) under the care of a man. He married her and she owned a date palm (garden). He married her just because of that and not because he loved her. So the Divine Verse came regarding his case: "If you fear that you shall not be able to deal justly with the orphan girls..." (4:3) The sub-narrator added: I think he (i.e. another sub-narrator) said, "That orphan girl was his partner in that date-palm (garden) and in his property."
