حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ الْوَرَكَانِيُّ، أَخْبَرَنَا إِبْرَاهِيمُ، - يَعْنِي ابْنَ سَعْدٍ - عَنِ الزُّهْرِيِّ، عَنْ سَهْلِ بْنِ سَعْدٍ، فِي خَبَرِ الْمُتَلاَعِنَيْنِ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَبْصِرُوهَا فَإِنْ جَاءَتْ بِهِ أَدْعَجَ الْعَيْنَيْنِ عَظِيمَ الأَلْيَتَيْنِ فَلاَ أُرَاهُ إِلاَّ قَدْ صَدَقَ وَإِنْ جَاءَتْ بِهِ أُحَيْمِرَ كَأَنَّهُ وَحَرَةٌ فَلاَ أُرَاهُ إِلاَّ كَاذِبًا ‏"‏ ‏.‏ قَالَ فَجَاءَتْ بِهِ عَلَى النَّعْتِ الْمَكْرُوهِ ‏.‏

Sahl bin Sa’ad reported the Apostle of Allaah(PBUH) as saying - in the tradition of spouses who invoked curses to each other “Look if she bears a child which has very black eyes, large buttocks, I cannot but imagine that he (i.e., ‘Uwaimir) has spoken the truth. But, if she bears a reddish child like the lizard with red spots (waharah), I cannot imagine that ‘Uwaimir has lied against her. She gave birth to a child (like that described the Prophet (PBUH) ) in a detestable manner. Translation Not Available
