Sahih Muslim Book 37, Hadith Number 6675.

Chapter : Hadith pertaining to the lie about (Hadrat) ‘Aisha Siddiqa (Allah be pleased with her) and accepting of Repentance of those who brought false allegation about her.

‘Aisha reported: When I came under discussion what the people had to say about me, Allah’s Messenger (may peace be upon him) stood up for delivering an address and he recited tashahhud (I bear witness to the fact that there is no god but Allah) and praised Allah, lauded Him what He rightly deserves and then said: Coming to the point. Give me an advice about them who have brought false charge about my family. By Allah, I know no evil in the members of my family and the person in connection with whom the false charge is being levelled, I know no evil in him too. And he never entered my house but in my presence and when I was away on a journey, he remained with me even in that. The rest of the hadith is the same but with this change that Allah’s Messenger (may peace be upon him) came to my house and asked my maidservant and she said: By Allah, I know no fault in her but this that she sleeps, and goat comes and eats the kneaded flour. Some of the Companions (of the Holy Prophet) scolded her and said: State the fact before Allah’s Messenger (may peace be upon him) and they even made a pointed reference (to this incident). She said: …By Allah, I know about her as does the jeweller know about the pure piece of gold. And when this news reached the person in connection with whom the allegation was made he said: Hallowed be Allah. By Allah, I have never unveiled any woman. ‘Aisha said: He fell as a martyr in the cause of Allah, and there is this addition in this hadith that the people who had brought false allegation amongst them were Mistah and Hamna and Hassan. And so far as the hypocrite ‘Abdullah b. Ubayy is concerned, he was one who tried his best to gather the false news and then gave them the wind. And he was in fact a fabricator and there was Hamna, daughter of Jahsh with him.
