عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ سُئِلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَا يَجُوزُ فِي الرَّضَاعَةِ مِنَ الشُّهُودِ قَالَ رَجُلٌ أَوِ امْرَأَةٌ وَسَمِعْتُهُ أَنَا مِنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ أَبِي شَيْبَةَ
It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) was asked how many witnesses are required in the case of breastfeeding. He (peace and blessings be upon him) replied: One man and one woman.
