← Previous Hadith It was narrated from Busr bin Sa'eed said that Zaid bin Khalid sent him to Abu Juhaim to ask him what he had heard the Messenger of Allah (ﷺ) say about one who passes in front of a person who is praying? Abu Juhaim said: "The Messenger of Allah(ﷺ)said: "If the one who passes in front of a person who is praying knew what (burden of sin) there is on him, standing for forty would be better for him than passing in front of him."

Sunan an-Nasa'i Book 9, Hadith 15 Next Hadith → It was narrated from Kathir bin Kathir, from his father, that his grandfather said: "I saw the Messenger of Allah (ﷺ) circumambulate the House seven times, then he prayed two Rak'ahs at the edge of the Maqam, and there was nothing between him and the people who were performing Tawaf."
