Was the Prophet's saying, peace be upon him, "Take what is sweet from her, take what is sweet from her" a praise for Zaynab due to her sincere intention in worship, or was it a rejection of her method of worship when she tied a rope in the mosque to assist herself in prayer?

The wording of the Hadith in Al-Sahih: On the authority of Anas (may Allah be pleased with him), he said: The Messenger of Allah (peace and blessings be upon him) entered, and there was a rope stretched between two pillars. He said: "What is this rope?" They said: "This is a rope for Zaynab; when she tires, she holds onto it." The Prophet (peace and blessings be upon him) said: "Untie it. Let each of you pray as long as he is energetic, and when he tires, let him sit down." And "untie it" (حلوه) is a command to untie the rope stretched for Zaynab, and not a description of sweetness (حلاوة).
