«كان إذا أراد سفرا أقرع بين نسائه فأيتهن خرج سهمها خرج بها معه»
It was the practice of the Prophet (peace and blessings be upon him):
"When he (peace and blessings be upon him) intended to travel, he would cast lots among his wives, and whichever of them had her lot drawn, he (peace and blessings be upon him) would take her with him."
