Musannaf Ibn Abi Shaybah

Hazrat Uqbah bin Harith narrates that I married the daughter of Abu Ihab Tamimi. Then, on the morning of her departure, a freed slave woman of Makkah came and said, "I have suckled both of you." Then Hazrat Uqbah rode to Madinah and presented the matter before the Holy Prophet (peace and blessings of Allah be upon him) and also said, "I asked the girl's family, but they denied it." The Holy Prophet (peace and blessings of Allah be upon him) said, "When it has been said, then what is the denial?" So he separated from her, and she married someone else.

Hazrat Ibn Umar (may Allah be pleased with them) narrates that the Messenger of Allah (peace and blessings be upon him) was asked: How many witnesses are sufficient in the case of breastfeeding (to establish fosterage)? The Prophet (peace and blessings be upon him) replied: One man or one woman. And (Imam) Abu Hanifa's opinion has been mentioned that: The testimony of more (witnesses) is acceptable, not of fewer.
