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”"
