Abu Sa’id Al Khudri said “A Bedouin asked the Prophet ﷺ about emigration. He replied “Woe to you! The matter of emigration is severe. Have you a Camel? He said, Yes. He asked “Do you pay its zakat? He said, Yes. He said, Then work (anywhere) beyond the seas. Allaah will not reduce anything from (the reward of) your work. (Using translation from Abū Dāʾūd 2477)  

أَنَّ أَعْرَابِيًّا سَأَلَ رَسُولَ اللهِ ﷺ عَنِ الْهِجْرَةِ فَقَالَ «وَيْحَكَ إِنَّ شَأْنَ الْهِجْرَةِ شَدِيدٌ فَهَلْ لَكَ مِنْ إِبِلٍ؟» قَالَ نَعَمْ قَالَ «فَهَلْ تُؤَدِّي صَدَقَتَهَا؟» قَالَ نَعَمْ قَالَ «فَاعْمَلْ مِنْ وَرَاءِ الْبِحَارِ فَإِنَّ اللهَ لَنْ يَتِرَكَ مِنْ عَمَلِكَ شَيْئًا»
