To behave in a suspicious and dishonest way; and to accuse others without proof
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، قَالَ ذَكَرَ ابْنُ عَبَّاسٍ الْمُتَلاَعِنَيْنِ فَقَالَ عَبْدُ اللَّهِ بْنُ شَدَّادٍ هِيَ الَّتِي قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لَوْ كُنْتُ رَاجِمًا امْرَأَةً عَنْ غَيْرِ بَيِّنَةٍ ". قَالَ لاَ، تِلْكَ امْرَأَةٌ أَعْلَنَتْ.
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 Messenger (ﷺ) 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).
