Anas told that when God’s Messenger went on an expedition he took Umm Sulaim, and he had some women of the Ansar who supplied water and tended the wounded when he made an expedition.
I went on seven expeditions with God's Messenger and stayed behind to look after the baggage, prepare food for them, tend the wounded and look after the sick.
When God’s Messenger intended to go on an expedition he always pretended to be going somewhere else till that expedition, meaning the one to Tabuk. God’s Messenger undertook it in extreme heat, facing a long journey, desert country and a numerous enemy. He made clear to the Muslims what they were about to do in order that they might get ready the equipment for their expedition, telling them where he was going.
