Sunan at-Tirmithiy كتاب الصوم باب ما جاء فيمن أكل ثم خرج يريد سفرا
Muḥammad Ibn-K'ab said, "I came to Anas Ibn-Mālik in Ramaḍān when he was about to travel; his baggage had been mounted onto his camel and he was dressed for travel. He called for food and ate. I asked, 'Is this a sunnah (the Prophet's tradition)?' 'It is,’ he replied, and he mounted."(1) Footnotes: (1) This hadīth shows that when one intends to travel it is permissible to eat while still at home, before setting off. Click on ḥadīth to read more
