Muhammad bin Kaab reported,

I came to Anas bin Malik during Ramadan as he was about to set out on a journey. His mount had been saddled for him and he had put on his traveling clothes. He called for food and ate.I asked him, "Is this the sunnah?"He replied, "It is the sunnah."Then he mounted and rode off.
