The reader: The author (may Allah have mercy on him) quoted:
"And from Anas (may Allah be pleased with him), who said: The Prophet (peace and blessings be upon him) entered the mosque and saw a rope stretched between the two pillars. He said: "What is this rope?" They said: "This is Zaynab's rope; when she gets tired, she holds onto it." The Prophet (peace and blessings be upon him) said: "Untie it. Let one of you pray while he has energy, and when he gets tired, let him sit down."
