عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ قَالَ: قَضَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي وَلَدِ الْمُتَلاَعِنَيْنِ: ((أَنَّهُ يَرِثُ أُمَّهُ وَتَرِثُهُ أُمُّهُ، وَمَنْ قَفَاهَا بِهِ جُلِدَ ثَمَانِينَ، وَمَنْ دَعَاهُ وَلَدَ زِنًا جُلِدَ ثَمَانِينَ))
Narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both): Regarding the children of those who perform li'an, the Messenger of Allah (peace and blessings be upon him and his family) gave this ruling: These children will belong to their mother, and their mother will be their heir. And whoever accuses this woman (of adultery), he will be given eighty (80) lashes, and whoever declares such children to be children of adultery, he will also be given eighty (80) lashes.
