Khadeeja's Friends
Aisha (radi Allahu anha) narrated: "I was not jealous of any wife of the Prophet (sal Allahu alaihi wa sallam) as I was jealous of Khadeeja (radi Allahu anha), and it was not because I saw her. It was only because the Messenger of Allah (sal Allahu alaihi wa sallam) mentioned her so much, and because whenever he would slaughter a sheep, he would look for Khadeeja's friends to gift them some of it." [Jami At-Tirmidhi - graded sahih]
If a man keeps good relations with someone in their life, he should continue these relations till the end. He should give the relatives and friends of his expired wife, parents, etc., the same consideration he used to during their lifetime. This is consistency in behaviour and constancy in character.
