He, was faithful to his wives and would safeguard their rights:

Under category: How He treated them?

The Messenger of Allah, sallallaahu ‘alayhi wa sallam, praised Khadeejah during her life and after her death, more than he praised any other wife. He, sallallaahu ‘alayhi wa sallam, was keen on highlighting her virtues and her status in his heart, and that she maintained this status even after her death.

‘Aa’ishah narrated: “Never did I feel jealous of the wives of the Messenger of Allah, sallallaahu ‘alayhi wa sallam, except in case of Khadeejah, although I did not (have the privilege to) see her. Whenever the Messenger of Allah, sallallaahu ‘alayhi wa sallam, slaughtered a sheep, he, sallallaahu ‘alayhi wa sallam, said: “Send it to the friends of Khadeejah.” One day I said to him: ‘(It is) Khadeejah only who always prevails upon your mind.’ Thereupon he, sallallaahu ‘alayhi wa sallam, said: “She was such and such a woman [praising her], and she was the mother of my children.””

Ibn Hajar (a scholar) said: “The Messenger of Allah, sallallaahu ‘alayhi wa sallam, never ceased praising her and mentioning her even after her death. Rather, he, sallallaahu ‘alayhi wa sallam, stayed faithful after her death and continued to praise her and mention her good traits and how wise and virtuous she was. All the children of the Messenger of Allah, sallallaahu ‘alayhi wa sallam, were from her, except Ibraaheem, whose mother was Maariyah. His children from her were two sons and four daughters, Al-Qaasim, Abdullaah (he was born after the Prophet of Allah, sallallaahu ‘alayhi wa sallam, was commissioned, and used to be also called At-Taahir and At-Tayyib) and his daughters were, Zaynab, Ruqayyah, Umm Kulthoom and Faatimah.
