What did the Prophet Muhammad (saw) usually do when he started a journey before noon?
 Narrated Anas bin Malik:                     Whenever the Prophet started the journey before noon, he used to delay the Zuhr prayer till the time for the `Asr prayer and then he would dismount and pray them together; and whenever the sun declined before he started the journey he used to offer the Zuhr prayer and then ride (for the journey).
