Lady Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The prayer for which the miswak is used is seventy times superior to the prayer for which the miswak is not used." Imam Abu Bakr (may Allah have mercy on him) says that I have made an exception regarding the authenticity of this hadith because I fear that Muhammad bin Ishaq did not hear this narration from Muhammad bin Muslim, but rather committed tadlis in it.
