Muhammad (one of the narrators) reported: I asked Anas b. Malik (Allah be pleased with him) knowing that he had a knowledge of (the case of li'an). He said: Hilal b. Umayya (Allah be pleased with him) accused his wife with the charge of fornication with Sharik b. Sahma, the brother of al-Bara'b Malik from the side of his mother. And he was the first person who invoked curse (li'an) in Islam. He in fact invoked curse upon her. Messenger of Allah ﷺ said: See to her if she gives birth to a white-complexioned child having dark hair and bright eyes;
he must be the son of Hilal b. Umayya;
and if she gives birth to a child with dark eyelids, curly hair and lean shanks, he must be the offspring of Sharik b. Sahma. He said: I was informed that she gave birth to a child having dark eyelids, curly hair and lean shanks.

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا هِشَامٌ، عَنْ مُحَمَّدٍ، قَالَ سَأَلْتُ أَنَسَ بْنَ مَالِكٍ وَأَنَا أُرَى، أَنَّ عِنْدَهُ، مِنْهُ عِلْمًا . فَقَالَ إِنَّ هِلاَلَ بْنَ أُمَيَّةَ قَذَفَ امْرَأَتَهُ بِشَرِيكِ ابْنِ سَحْمَاءَ وَكَانَ أَخَا الْبَرَاءِ بْنِ مَالِكٍ لأُمِّهِ وَكَانَ أَوَّلَ رَجُلٍ لاَعَنَ فِي الإِسْلاَمِ - قَالَ - فَلاَعَنَهَا فَقَالَ رَسُولُ اللَّهِ ﷺ
" أَبْصِرُوهَا فَإِنْ جَاءَتْ بِهِ أَبْيَضَ سَبِطًا قَضِيءَ الْعَيْنَيْنِ فَهُوَ لِهِلاَلِ بْنِ أُمَيَّةَ وَإِنْ جَاءَتْ بِهِ أَكْحَلَ جَعْدًا حَمْشَ السَّاقَيْنِ فَهُوَ لِشَرِيكِ ابْنِ سَحْمَاءَ " . قَالَ فَأُنْبِئْتُ أَنَّهَا جَاءَتْ بِهِ أَكْحَلَ جَعْدًا حَمْشَ السَّاقَيْنِ .
