I was thinking about this narration about an interaction that Umar RA had regarding someone who actually knows the other. It is pasted below for reference: Kharashah ibn al-Hurr reported: A man gave his testimony to Umar ibn al-Khattab, may Allah be pleased with him. Umar said to him, “I do not know you and it will not harm you that I do not know. Bring someone who knows you.” A man from his people said, “I know him.” Umar said, “What do you know about him?” The man said, “His justice and virtue.” Umar said, “Is he your closest neighbor, such that you know him by his coming and going by day and night?” The man said no. Umar said, “Then, have you had business dealings with him, by which you are shown his piety?” The man said no. Umar said, “Then, have you travelled with him on a journey, by which you are shown his good character?” The man said no. Umar said, “You do not know him.” Umar turned to the witness and said, “Bring me someone who knows you.” Source: al-Sunan al-Kubrá 19769 Grade: Sahih (authentic) according to Al-Albani https://www.abuaminaelias.com/dailyhadithonline/2014/01/13/umar-how-do-you-know/ I do not want this to be taken out of context in any way; I think there are some interesting points that can be understood from this. The man he is talking to says he knows someone for "His justice and virtue." Umar RA then questions him about how he claims to know this. Umar RA points out some situations where someone can say they actually know another person: 1. "Is he your closest neighbour?" - A neighbour - Islam places high emphasis on dealing well with our neighbours; not only should their testimony about us be good, but they have seen us on ordinary days, day in and day out and have either felt our presence or absence. 2.Umar RA then asks "Then have you had business dealings with him..." and makes the correlation to piety. - Business dealings - honesty and trustworthiness, but also patience... how is he when dealing with transactions that may not be favourable, etiquette and more
