"We went to Abu Sa'eed and he said: 'Welcome with the exhortation of the Messenger of Allah ﷺ. Indeed the Prophet ﷺ said: "Surely, the people are followers of you, and men will certainly come to you from the regions of the earth to gain understanding in the religion. So when they come to you exhort them with good."  

كُنَّا نَأْتِي أَبَا سَعِيدٍ فَيَقُولُ مَرْحَبًا بِوَصِيَّةِ رَسُولِ اللَّهِ ﷺ إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ النَّاسَ لَكُمْ تَبَعٌ وَإِنَّ رِجَالاً يَأْتُونَكُمْ مِنْ أَقْطَارِ الأَرَضِينَ يَتَفَقَّهُونَ فِي الدِّينِ فَإِذَا أَتَوْكُمْ فَاسْتَوْصُوا بِهِمْ خَيْرًا  

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
