Hazrat Abu Sa'id Khudri (may Allah be pleased with him) narrated that a Bedouin asked the Messenger of Allah (peace and blessings be upon him) about migration (that is, whether he should be permitted to migrate to Madinah). The Prophet (peace and blessings be upon him) said: Alas! Its status is indeed great. Do you have some camels for which you pay zakat? He said: Yes! Upon this, the Prophet (peace and blessings be upon him) said: Then what is there (to worry about)? Keep performing deeds (wherever you are), even across the seas (in whichever country you reside), Allah will not diminish the reward of any of your deeds.
