A man came to the Prophet ﷺ and asked him about emigration.The Prophet ﷺ said, "Woe to you, the matter of emigration is a serious one. Do you have any camels?"The man replied, "Yes."He asked, "Do you pay the charity due on them?"He replied, "Yes."He asked, "Do you lend them out for others to benefit from?"He replied, "Yes."He asked, "Do you milk them on the day they come to water?"He replied, "Yes."The Prophet ﷺ said, "Then work from beyond the seas, for Allah will never let any of your deeds go to waste."
حدثنا معاوية بن عمرو حدثنا أبو إسحاق الفزاري عن الأوزاعي عن الزهري عن عطاء بن يزيد
جاء رجل إلى النبي ﷺ فسأله عن الهجرة فقال ويحك إن الهجرة شأنها شديد فهل لك من إبل قال نعم قال هل تؤدي صدقتها قال نعم قال هل تمنح منها قال نعم قال هل تحلبها يوم وردها قال نعم قال فاعمل من وراء البحار فإن الله لن يترك من عملك شيئا
