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.'"
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
