AbuAyyub heard the Messenger of Allah ﷺ say: Capitals will be conquered at your hands, and you will have to raise companies in large armies. A man will be unwilling to join a company, so he will escape from his people and go round the tribes offering himself to them, saying: Whose place may I take in such and such expedition? Whose place may I take in such and such expedition? Beware: That man is a hireling to the last drop of his blood.  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ سَتُفْتَحُ عَلَيْكُمُ الأَمْصَارُ وَسَتَكُونُ جُنُودٌ مُجَنَّدَةٌ تُقْطَعُ عَلَيْكُمْ فِيهَا بُعُوثٌ فَيَكْرَهُ الرَّجُلُ مِنْكُمُ الْبَعْثَ فِيهَا فَيَتَخَلَّصُ مِنْ قَوْمِهِ ثُمَّ يَتَصَفَّحُ الْقَبَائِلَ يَعْرِضُ نَفْسَهُ عَلَيْهِمْ يَقُولُ مَنْ أَكْفِيهِ بَعْثَ كَذَا مَنْ أَكْفِيهِ بَعْثَ كَذَا أَلاَ وَذَلِكَ الأَجِيرُ إِلَى آخِرِ قَطْرَةٍ مِنْ دَمِهِ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّهَا سَتُفْتَحُ عَلَيْكُمُ الْأَمْصَارُ وَسَيَضْرِبُونَ عَلَيْكُمْ فِيهَا بُعُوثًا يُنْكِرُ الرَّجُلُ مِنْكُمُ الْبَعْثَ فَيَتَخَلَّصُ مِنْ قَوْمِهِ وَيَعْرِضُ نَفْسَهُ عَلَى الْقَبَائِلِ يَقُولُ مَنْ أَكْفِيهِ بَعْثَ كَذَا وَكَذَا أَلَا وَذَلِكَ الْأَجِيرُ إِلَى آخِرِ قَطْرَةٍ مِنْ دَمِهِ  

"سَتُفْتَحُ عَلَيْكُمُ الأَمْصَارُ، وَسَتَكُون جُنُودٌ مُجَنَّدَةٌ تُقْطَعُ عَلَيْكُمْ فيها بُعُوثٌ فَيَكْرَهُ الرَّجُلُ مِنْكُمْ البَعْثَ فِيهَا، فَيَتَخَلَّصُ مِنْ قَوْمِهِ، ثُمَّ يَتَصَفَّحُ الْقَبَائِلَ يَعْرضُ نَفْسَهُ عَلَيْهِمْ، يَقُولُ: مَن أَكْفِهِ بَعْثَ كَذَا؟ مَن أَكْفِهِ بَعْثَ كَذَا؟ ألاَ وَذَلِكَ الأَخْيرُ إِلى آخِرِ قَطْرَةٍ مِنْ دَمِهِ".
