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)
حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، عَنْ أَبِي بَكْرِ بْنِ عَيَّاشٍ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، قَالَ جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ ‏:‏ ‏(‏ يَسْتَفْتُونَكَ قُلِ اللَّهُ يُفْتِيكُمْ فِي الْكَلاَلَةِ ‏)‏ فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم ‏"‏ تُجْزِيكَ آيَةُ الصَّيْفِ ‏"‏ ‏.‏
