What did Prophet Muhammad (saw) do when he offered four rak`at of the Zuhr prayer in Medina and two rak`at of `Asr prayer at Dhul-Hulaifa?
 Narrated Abu Qilaba:                     Anas bin Malik said, "The Prophet offered four rak`at of the Zuhr prayer in Medina and two rak`at of `Asr prayer at Dhul-Hulaifa." I think that the Prophet passed the night there till morning.
