Narrated `Uqba bin Al-Harith:

I married a woman and then a black lady came to us and said, "I have suckled you both (you and your wife)." So I came to the Prophet (ﷺ) and said, "I married so-and-so and then a black lady came to us and said to me, 'I have suckled both of you.' But I think she is a liar." The Prophet (ﷺ) turned his face away from me and I moved to face his face, and said, "She is a liar." The Prophet (ﷺ) said, "How (can you keep her as your wife) when that lady has said that she has suckled both of you? So abandon (i.e., divorce) her (your wife).

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا أَيُّوبُ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي مُلَيْكَةَ، قَالَ حَدَّثَنِي عُبَيْدُ بْنُ أَبِي مَرْيَمَ، عَنْ عُقْبَةَ بْنِ الْحَارِثِ، قَالَ وَقَدْ سَمِعْتُهُ مِنْ، عُقْبَةَ لَكِنِّي لِحَدِيثِ عُبَيْدٍ أَحْفَظُ قَالَ تَزَوَّجْتُ امْرَأَةً، فَجَاءَتْنَا امْرَأَةٌ سَوْدَاءُ فَقَالَتْ أَرْضَعْتُكُمَا‏.‏ فَأَتَيْتُ النَّبِيَّ صلى الله عليه وسلم فَقُلْتُ تَزَوَّجْتُ فُلاَنَةَ بِنْتَ فُلاَنٍ فَجَاءَتْنَا امْرَأَةٌ سَوْدَاءُ فَقَالَتْ لِي إِنِّي قَدْ أَرْضَعْتُكُمَا‏.‏ وَهْىَ كَاذِبَةٌ فَأَعْرَضَ، فَأَتَيْتُهُ مِنْ قِبَلِ وَجْهِهِ، قُلْتُ إِنَّهَا كَاذِبَةٌ‏.‏ قَالَ ‏

‏ كَيْفَ بِهَا وَقَدْ زَعَمَتْ أَنَّهَا قَدْ أَرْضَعَتْكُمَا، دَعْهَا عَنْكَ ‏

‏ وَأَشَارَ إِسْمَاعِيلُ بِإِصْبَعَيْهِ السَّبَّابَةِ وَالْوُسْطَى يَحْكِي أَيُّوبَ‏.‏
