Jami` at-Tirmidhi 3042

Narrated Al-Bara:"A man came to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah! They ask you about a legal verdict. Say: "Allah directs (thus) regarding Al-Kalalah (4:176)." So the Prophet (ﷺ) said to him: "You should be sufficed with the Ayah of summer." (Meaning this Ayah, while in An-Nisa number 12, is mention of the topic, and it was revealed in the winter, this Ayah, revealed in the summer - the last revealed about it - explains it)
