I took Abu Mabad to the Prophet ﷺ in order that he might give him the pledge of allegiance for migration. The Prophet ﷺ said, "Migration has gone to its people, but I take the pledge from him (i.e. Abu Mabad) for Islam and Jihad."  

عَنْ مُجَاشِعِ بْنِ مَسْعُودٍ انْطَلَقْتُ بِأَبِي مَعْبَدٍ إِلَى النَّبِيِّ ﷺ لِيُبَايِعَهُ عَلَى الْهِجْرَةِ قَالَ مَضَتِ الْهِجْرَةُ لأَهْلِهَا أُبَايِعُهُ عَلَى الإِسْلاَمِ وَالْجِهَادِ فَلَقِيتُ أَبَا مَعْبَدٍ فَسَأَلْتُهُ فَقَالَ صَدَقَ مُجَاشِعٌ وَقَالَ خَالِدٌ عَنْ أَبِي عُثْمَانَ عَنْ مُجَاشِعٍ أَنَّهُ جَاءَ بِأَخِيهِ مُجَالِدٍ  

The Prophet ﷺ said, on the day of the Conquest of Mecca, "There is no migration (after the Conquest), but Jihad and good intentions, and when you are called for Jihad, you should immediately respond to the call."  

قَالَ النَّبِيُّ ﷺ يَوْمَ فَتْحِ مَكَّةَ لاَ هِجْرَةَ وَلَكِنْ جِهَادٌ وَنِيَّةٌ وَإِذَا اسْتُنْفِرْتُمْ فَانْفِرُوا  

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
