Narrated Al-Qasim bin Muhammad:
Ibn 'Abbas mentioned the couple who had taken the oath of Lian. 'Abdullah bin Shaddad said (to him), "Was this woman about whom Allah's Apostle said, 'If I were ever to stone to death any woman without witnesses. (I would have stoned that woman to death)?' Ibn 'Abbas replied," No, that lady exposed herself (by her suspicious behavior)."
