This Hadīth shows how the Prophet (may Allah's peace and blessings be upon him) taught his Ummah. He was keen on establishing good relations among Muslims through visits and communication, especially visiting the sick. 'Abdullah ibn' Umar (may Allah be pleased with him and his father) narrates that some of the Companions (may Allah be pleased with them) were sitting with the Prophet (may Allah's peace and blessings be upon him), and this was the Companions' habit with the Prophet (may Allah's peace and blessings be upon him), i.e., gathering around him to teach and guide them. During this session, a man from the Ansār - people of Madīnah - came to him and greeted the Prophet (may Allah's peace and blessings be upon him) and those who were present, which is the etiquette of Islam in extending the greeting of peace to all. After greeting the Prophet (may Allah's peace and blessings be upon him), the Ansāri man wanted to leave. So, the Messenger of Allah (may Allah's peace and blessings be upon him) said in a pleasant way: "O brother of the Ansār, how is my brother Sa‘d ibn ‘Ubādah?" Sa'd (may Allah be pleased with him) was the chief of the Khazraj, and he was sick then. Here, the Prophet (may Allah's peace and blessings be upon him) was teaching Muslims to ask after each other in case of being absent or falling sick. His saying: "O brother of the Ansār", is a call by the brotherhood of Islam and a call for the man to show that he was from the Ansār, besides the act of honoring Sa'd ibn' Ubādah as the Prophet (may Allah's peace and blessings be upon him) called him: "My brother". Answering the Prophet's question, the man said: He is "good," i.e., no worry about him, as he is still alive and is likely to recover from his sickness, which is a polite thing to say and is said as a form of being optimistic that the patient will recover and be healthy once again. Thereupon, the Messenger of Allah (may Allah's peace and blessings be upon him) encouraged his Companions to visit him, saying: "Who among you would visit him?" This was how the Prophet (may Allah's peace and blessings be upon him) practically taught Muslims, as he got up along with his Companions to visit Sa'd ibn' Ubādah (may Allah be pleased with him), and they were "bid'at 'ashr" (more than ten), and "bid '" is: from three to ten. At this time, those who were present from among the Companions were suffering from indigence and poverty to the extent that 'Abdullah ibn' Umar (may Allah be pleased with him) said: "We were wearing neither Ni‘āl (shoes)", plural of "Na‘l", which is the shoe, "nor Khifāf (leather socks)", plural of "Khuff", which is footwear made of thin leather. In other words, they had nothing to wear on their feet. "Nor Qalānis (caps)", plural of "Qalansuwah", which is something worn on the head, "nor Qumus (shirts)", plural of "Qamīs", which is a sewn undergarment having two sleeves, or that which is made either of cotton or linen and this means that they were wearing Izār (lower garment) and Ridā' (upper garment). They went walking on foot to the house of Sa'd ibn' Ubādah (may Allah be pleased with him) "on such swampy ground," which is the earth that is highly saline and nothing grows therein except some trees, i.e., they were wearing nothing on their feet to protect them from the harm of such ground. When the Prophet (may Allah's peace and blessings be upon him) reached the house of Sa‘d (may Allah be pleased with him), Sa‘d's people, family, and kinfolk moved from around him to give the Prophet (may Allah's peace and blessing be upon him) and his Companions who came to visit him the chance to proceed and get close to him, which is part of the visit etiquettes and honoring guests. The Hadīth encourages asking after the absent and the sick and shows how the Prophet (may Allah's peace and blessings be upon him) used to ask after his Companions. It prompts us to visit the sick and communicate with them. It points out the indigence and poverty of some of the Companions and how far they were from lavish in their clothes and their appearance. It sheds light on honoring the guest who comes to visit by making room for him. It shows that whoever has no shoes may walk barefoot..
