A Bedouin asked Messenger of Allah ﷺ about the emigration. The Prophet ﷺ said, "May Allah have mercy on you! The matter of emigration is very hard. Have you got camels? Do you pay their Zakat?" The Bedouin said, "Yes, I have camels and I pay their Zakat." The Prophet ﷺ said, Work beyond the seas and Allah will not decrease (waste) any of your good deeds." (See Hadith No. 260 Vol. 5).  

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ؓ أَنَّ أَعْرَابِيًّا سَأَلَ رَسُولَ اللَّهِ ﷺ عَنِ الْهِجْرَةِ فَقَالَ وَيْحَكَ إِنَّ شَأْنَهَا شَدِيدٌ فَهَلْ لَكَ مِنْ إِبِلٍ تُؤَدِّي صَدَقَتَهَا قَالَ نَعَمْ قَالَ فَاعْمَلْ مِنْ وَرَاءِ الْبِحَارِ فَإِنَّ اللَّهَ لَنْ يَتِرَكَ مِنْ عَمَلِكَ شَيْئًا
