Narrated Abu Sa`id:Once a bedouin came to the Prophet (ﷺ) and asked him about the migration. The Prophet (ﷺ) said, "Mercy of Allah be on you! The migration is a quite difficult matter. Have you got some camels?" He replied in the affirmative. Then the Prophet (ﷺ) said, "Do you give their Zakat?" He replied in the affirmative. The Prophet said, "Do you let others benefit by their milk gratis?" He replied in the affirmative. Then the Prophet asked, "Do you milk them on their watering days and give their milk to the poor and needy?" He replied in the affirmative. The Prophet, said, "Go on doing like this from beyond the seas, and there is no doubt that Allah will not overlook any of your good deeds
