Sahih Muslim — The Book on Government — Hadith No: 4826
حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ أَبُو جَعْفَرٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّاءَ، عَنْ عَاصِمٍ الأَحْوَلِ، عَنْ أَبِي عُثْمَانَ النَّهْدِيِّ، حَدَّثَنِي مُجَاشِعُ بْنُ مَسْعُودٍ السُّلَمِيُّ، قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم أُبَايِعُهُ عَلَى الْهِجْرَةِ فَقَالَ " إِنَّ الْهِجْرَةَ قَدْ مَضَتْ لأَهْلِهَا وَلَكِنْ عَلَى الإِسْلاَمِ وَالْجِهَادِ وَالْخَيْرِ " .
Translation
It has been reported on the authority of Mujashi' b. Mas'ud as-Sulami who said:I came to the Prophet (ﷺ) to offer him my pledge of migration. He said: The period of migration has expired (and those who wereto get the reward for this great act of devotion have got it). You may now give your pledge to serve the cause of Islam, to strive in the way of Allah and to follow the path of virtue
