Prophet's Justice
2 hadiths
Indeed, you are not inferior in the sight of your family. If you wish, I can stay seven (nights) with you, but if I stay seven with you, I will also stay seven with my (other) wives
Umm Salamah (may Allah be pleased with her) reported that when the Messenger of Allah (may Allah's peace and blessings be upon him) married her, he stayed three nights with her and said: "Indeed, you are not inferior in the sight of your family. If you wish, I can stay seven (nights) with you, but if I stay seven with you, I will also stay seven with my (other) wives."
Whenever the Prophet (may Allah's peace and blessings be upon him) intended to go on a journey, he would cast lots among his wives and would take the one on whom the lot fell
‘Ā'ishah (may Allah be pleased with her) reported: Whenever the Prophet (may Allah's peace and blessings be upon him) intended to go on a journey, he would cast lots among his wives and would take the one on whom the lot fell. Once, before setting out for a battle, he drew lots among us and the lot fell to me; so I went with the Prophet, may Allah's peace and blessings be upon him; and that happened after the revelation of (the verse on) Hijāb.
