What conditions allowed `Aisha and Um Mistah to recall the narrative regarding 'Aisha, the wife of the Prophet Muhammad (saw)?
 Narrated Yunus bin Yazid:                     I heard Az-Zuhri saying, "I heard `Urwa bin Az-Zubair. Sa`id bin Al-Musaiyab, 'Alqama bin Waqqas and 'Ubaidullah bin `Abdullah each narrating part of the narrative concerning `Aisha the wife of the Prophet. `Aisha said: When I and Um Mistah were returning, Um Mistah stumbled by treading on the end of her robe, and on that she said, 'May Mistah be ruined.' I said, 'You have said a bad thing, you curse a man who took part in the battle of Badr!." Az-Zuhri then narrated the narration of the Lie (forged against `Aisha).
