Busr bin Sa'id says that once Zaid bin Khalid (may Allah be pleased with him) sent me to Abu Juhaim (may Allah be pleased with him) to ask about the hadith he had heard regarding a person passing in front of someone who is praying. He said: I heard the Prophet (peace and blessings of Allah be upon him) say that it is better for a person to stand and wait for forty ________ than to pass in front of someone who is praying. I do not remember whether the Prophet (peace and blessings of Allah be upon him) said days, months, or years.
