He sent the present to khadija’s friend
 

Hazrat Khadija had died many years ago. She had been buried in Makkah. Hazrat Muhammad (pbuh) had migrated to Madinah. A friend of Khadija’s was among the ones that migrated to Madinah. According to what Anas bin Malik, his servant, narrates, when something was given him as a present, he usually sent the present to that woman. He said,

"She was Khadija's friend. She loved Khadija a lot."

Hazrat Muhammad (pbuh) never forgot Hazrat Khadija, his first wife.
