[Machine] The Messenger of Allah ﷺ was sitting at Quba' with a group of people when Mus'ab ibn 'Umair came to him wearing a garment that barely covered him, and his people were poor. He greeted them and they returned his greeting. The Prophet ﷺ praised him and spoke highly of him. Then he said, "I have seen him with his parents in Makkah, they used to honor him and treat him kindly, and there was no young man from the Quraish like him. Then he left all that seeking the pleasure of Allah and the support of His Messenger. Know that he will not come to you except like this and this until Persia and Rome are opened before you. One of you would go in the morning wearing a dress and in the evening he would be wearing something else, and he would have breakfast with you in one place and have dinner with you in another place." They said, "O Messenger of Allah, are we better today or that day?" He said, "No, you are better today than you were on that day. If only you knew what I know of this world, you would have been at peace with it." Adh-Dhahabi remained silent about this in his summary.  

كَانَ رَسُولُ اللَّهِ ﷺ جَالِسًا بِقُبَاءَ وَمَعَهُ نَفَرٌ فَقَامَ مُصْعَبُ بْنُ عُمَيْرٍ عَلَيْهِ بُرْدَةٌ مَا تَكَادُ تُوَارِيهِ وَنَكَسَ الْقَوْمُ فَجَاءَ فَسَلَّمَ فَرَدُّوا عَلَيْهِ فَقَالَ فِيهِ النَّبِيُّ ﷺ خَيْرًا وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ «لَقَدْ رَأَيْتُ هَذَا عِنْدَ أَبَوَيْهِ بِمَكَّةَ يُكْرِمَانِهِ يُنَعِّمَانِهِ وَمَا فَتًى مِنْ فَتَيَانِ قُرَيْشٍ مِثْلُهُ ثُمَّ خَرَجَ مِنْ ذَلِكَ ابْتِغَاءَ مَرْضَاتِ اللَّهِ وَنُصْرَةِ رَسُولِهِ أَمَا أَنَّهُ لَا يَأْتِي عَلَيْكُمْ إِلَّا كَذَا وَكَذَا حَتَّى يُفْتَحَ عَلَيْكُمْ فَارِسُ وَالرُّومُ فَيَغْدُو أَحَدُكُمْ فِي حُلَّةٍ وَيَرُوحُ فِي حُلَّةٍ وَيُغْدَى عَلَيْكُمْ بِقَصْعَةٍ وَيُرَاحُ عَلَيْكُمْ بِقَصْعَةٍ» قَالُوا يَا رَسُولَ اللَّهِ نَحْنُ الْيَوْمَ خَيْرٌ أَوْ ذَلِكَ الْيَوْمَ قَالَ «بَلْ أَنْتُمُ الْيَوْمَ خَيْرٌ مِنْكُمْ ذَلِكَ الْيَوْمَ أَمَا لَوْ تَعْلَمُونَ مِنَ الدُّنْيَا مَا أَعْلَمُ لَاسْتَرَاحَتْ أَنْفُسُكُمْ مِنْهَا» سكت عنه الذهبي في التلخيص
