Sahih Bukhari Volume 3, Book 34, Hadith 2053

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ بْنِ أَبِي حُسَيْنٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَبِي مُلَيْكَةَ، عَنْ عُقْبَةَ بْنِ الْحَارِثِ ـ رضى الله عنه ـ أَنَّ امْرَأَةً، سَوْدَاءَ جَاءَتْ، فَزَعَمَتْ أَنَّهَا أَرْضَعَتْهُمَا، فَذَكَرَ لِلنَّبِيِّ فَأَعْرَضَ عَنْهُ، وَتَبَسَّمَ النَّبِيُّ صلى الله عليه وسلم‏.‏ قَالَ ‏"‏ كَيْفَ وَقَدْ قِيلَ ‏"‏‏.‏ وَقَدْ كَانَتْ تَحْتَهُ ابْنَةُ أَبِي إِهَابٍ التَّمِيمِيِّ‏.‏

Narrated By Abdullah bin Abu Mulaika : Uqba bin Al-Harith said that a black woman came and claimed that she had suckled both of them (i.e. 'Uqba and his wife). So, he mentioned that to the Prophet who turned his face from him and smiled and said, "How (can you keep your wife), and it was said (that both of you were suckled by the same woman)?" His wife was the daughter of Abu Ihab-al-Tamimi.
