Jarir bin 'Abdul Hameed al-Razi جرير بن عبد الحميد أبو عبد الله الضبي · The Book of al-Bay'ah

a Bedouin asked the Messenger of Allah about emigration (Hijrah). He said: "Woe to you, emigration is very important. Do you have any camels?" He said: "Yes. He said: "Do you pay Sadaqah on them?" He said: "Yes." He said: "Do righteous deeds no matter how far away you are from the Muslims, for Allah, the Mighty and sublime, will never cause any of your deeds tobe lost."

"O Messenger of Allah, tell me of an action that I may do and persist in it." The Messenger of Allah said to him: "You should emigrate, for there is nothing like it."
