It was narrated from Anas, that the Messenger of Allah had a female slave with whom he had intercourse, but 'Aishah and Hafsah would not leave him alone until he said that she was forbidden for him. Then Allah, the Mighty and Sublime, revealed:
"O Prophet! Why do you forbid (for yourself) that which Allah has allowed to you.' until the end of the Verse.

Tafsir of ibn Kathir on Qur'an 66:1-3
The messenger of Allah, peace and prayer of Allah be upon him, was having sexual relations with a female slave which he had, but Aisha and Hafsa would not cease to bother him about it until he forbid himself to continue it, until Allah praised and glorious brought down a verse saying "O prophet, why do you forbid to yourself what Allah has allowed" until the end of the verse. Ibn Jarir said...The messenger of Allah, peace and prayer of Allah be upon him had sex with Um Ibrahim (Mariyah Al-Qibtiyah) in the house of some of his women. Then she (Hafsah?) said "Hey messenger of Allah! In my house and upon my bed?!" Then the prophet made it forbidden (for him to have sex with her). Then she said "Hey messenger of Allah, how will you forbid what is allowed to you?" Then he swore not to have sex with her. Then Allah revealed "Oh prophet why do you forbid what Allah has made allowable to you?"

* تفسير Tafsir al-Jalalayn - Q 66: 1
{ يٰأَيُّهَا ٱلنَّبِيُّ لِمَ تُحَرِّمُ مَآ أَحَلَّ ٱللَّهُ لَكَ تَبْتَغِي مَرْضَاتَ أَزْوَاجِكَ وَٱللَّهُ غَفُورٌ رَّحِيمٌ }
O Prophet! Why do you prohibit what God has made lawful for you in terms of your Coptic handmaiden Māriya — when he lay with her in the house of Hafsa who had been away but who upon returning and finding out became upset by the fact that this had taken place in her own house and on her own bed — by saying ‘She is unlawful for me!’ seeking by making her unlawful for you to please your wives? And God is Forgiving Merciful having forgiven you this prohibition.

Q 66:2
{ قَدْ فَرَضَ ٱللَّهُ لَكُمْ تَحِلَّةَ أَيْمَانِكُمْ وَٱللَّهُ مَوْلاَكُمْ وَهُوَ ٱلْعَلِيمُ ٱلْحَكِيمُ }
Verily God has prescribed He has made lawful for you when necessary the absolution of your oaths to absolve them by expiation as mentioned in the sūrat al-Mā’ida Q. 589 and the forbidding of sexual relations with a handmaiden counts as an oath so did the Prophet s expiate? Muqātil b. Sulaymān said ‘He set free a slave in expiation for his prohibition of Māriya’; whereas al-Hasan al-Basrī said ‘He never expiated because the Prophet s has been forgiven all errors’. And God is your Protector your Helper and He is the Knower the Wise.

Q 66:3
{ وَإِذْ أَسَرَّ ٱلنَّبِيُّ إِلَىٰ بَعْضِ أَزْوَاجِهِ حَدِيثاً فَلَمَّا نَبَّأَتْ بِهِ وَأَظْهَرَهُ ٱللَّهُ عَلَيْهِ عَرَّفَ بَعْضَهُ وَأَعْرَضَ عَن بَعْضٍ فَلَمَّا نَبَّأَهَا بِهِ قَالَتْ مَنْ أَنبَأَكَ هَـٰذَا قَالَ نَبَّأَنِيَ ٱلْعَلِيمُ ٱلْخَبِيرُ }
And mention when the Prophet confided to one of his wives namely Hafsa a certain matter which was his prohibition of Māriya telling her ‘Do not reveal it!’; but when she divulged it to ‘Ā’isha reckoning there to be no blame in doing such a thing and God apprised him He informed him of it of what had been divulged he announced part of it to Hafsa and passed over part out of graciousness on his part. So when he told her about it she said ‘Who told you this?’ He said ‘I was told by the Knower the Aware’ namely God.
