10. It is narrated from him (narrator of the Hadith above) from ‘Uthman ibn ‘Isa from Muhammad ibn ‘Ajlan who has said the following: “Once, I was in the presence of Abu ‘Abdillah عليه السلام when a man came and offered the greeting of peace. The Imam asked, ‘How are your brothers (in belief) whom you have left behind?’ He praised, admired and extolled them. The Imam asked, ‘Do their wealthy ones visit their poor ones?’ He said, ‘It is very rare.’ The Imam asked, ‘Do their rich ones reach out to the poor ones?’ He said, ‘It is very rare.’ “The Imam asked, ‘Do their rich ones maintain good relations with their poor ones financially?’ He said, ‘You are speaking of the moral behavior that is practiced very rarely in our people.’ The narrator has said that the Imam then asked, ‘Why do you then think they are Shi’a (Muslims)?”’
