Narrated Abu Harun [Al-'Abdi]:

from Abu Sa'eed Al-Khudri that the Prophet ﷺ said: "Men will come to you from the direction of the east to learn. So when they come to you then exhort them to good." He said: "When Abu Sa'eed saw us he would say: 'Welcome with the exhortation of the Messenger of Allah, may the peace and blessings of Allah be upon him and his family.'"

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا نُوحُ بْنُ قَيْسٍ، عَنْ أَبِي هَارُونَ الْعَبْدِيِّ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، عَنِ النَّبِيِّ ﷺ قَالَ " يَأْتِيكُمْ رِجَالٌ مِنْ قِبَلِ الْمَشْرِقِ يَتَعَلَّمُونَ فَإِذَا جَاءُوكُمْ فَاسْتَوْصُوا بِهِمْ خَيْرًا " . قَالَ فَكَانَ أَبُو سَعِيدٍ إِذَا رَآنَا قَالَ مَرْحَبًا بِوَصِيَّةِ رَسُولِ اللَّهِ ﷺ . قَالَ هَذَا حَدِيثٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ أَبِي هَارُونَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ .
