The Prophet would divide (his time) equally between his wives and said: "O Allah! This is my division in what I have control over, so do not punish me for what You have control over which I do not have control over."
Jami` at-Tirmidhi Book 11, Hadith 62
← Previous Hadith He (Abu Qilabah) said: "If I wish, I could say: 'The Messenger of Allah said'" but he said: "The Sunnah when a man married a virgin after he already has a wife, is that he stays with her seven (nights). And when he married a matron when he already has a wife, he stays with her three (nights)."

Jami` at-Tirmidhi Book 11, Hadith 61 Next Hadith → The Messenger of Allah said: "When a man has two wives and he is not just between them, he will come on the Day of Judgment with one side drooping."
