How did the Prophet, peace and blessings be upon him, cast lots among his wives when he intended to travel?

When the Prophet (peace and blessings be upon him) intended to travel, he would cast lots among his wives. This was out of his complete justice and excellent companionship. There is no explicit text detailing the exact method of casting lots, but scholars have mentioned that its form involves writing the names of those participating in the lot on slips of paper or similar items, then instructing an unrelated person to choose a slip. Whoever's name appears is then the one entitled. The Sharia has not specified a particular method for casting lots, so any method by which it is carried out is permissible.
