In Madinah, Prophet Muhammad (peace be upon him) used to set aside time every morning to teach his Companions. He was renowned for his eloquence and clarity of speech. He did not speak too quickly, and although his phrasing was precise, he did not speak slowly or in fragments with numerous pauses. It was easy for everyone to follow what he said.
A’ishah described his way of speaking as follows: “Allah’s Messenger did not ramble on the way you do these days. His speech was clear and precise. Those who listened to him easily remembered what he said.” [Sahih al-Bukhari (3568) and Sahih Muslim (2493)]
Almost every day, he would sit in the mosque in Madinah with his Companions gathered around him. He would often start a discussion by posing a question. Once, he asked: “Might I inform you of the gravest of major sins?” When his Companions replied in the affirmative, he said: “The gravest of major sins are to associate partners in worship with Allah, to disrespect your parents, and to bear false witness.” [Sahih al-Bukhari (2654)]
Sometimes, he posed questions to open their eyes to a new idea or perspective that they had not considered before. For instance, once he asked, “Do you know what it means to be bankrupt?” They replied that it means to possess neither money nor goods. He said: With respect to my followers, the one who is bankrupt is one who is brought forth on the day of judgment with prayers, fasts, and charity to his credit, but he had spoken ill of some people, falsely accused some people, misappropriated the wealth of others, and assaulted people or shed their blood. Those he had wronged will be compensated from his good deeds until he has no more to his credit. Then the remainder of those he had wronged will be compensated by having some of their sins placed on him. As a consequence, he is consigned to Hell. [Sahih Muslim (2581)]
