Narrated Al-Bara' ibn Azib:

A man came to the Prophet ﷺ and said: Messenger of Allah, they ask thee for a legal decision about a kalalah. What is meant by kalalah? He replied: The verse revealed in summer is sufficient for you.

I asked AbuIshaq: Does it mean a person who dies and leaves neither children nor father? He said: This is so. The people think it is so.

حَدَّثَنَا مَنْصُورُ بْنُ أَبِي مُزَاحِمٍ، حَدَّثَنَا أَبُو بَكْرٍ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، قَالَ جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ يَسْتَفْتُونَكَ فِي الْكَلاَلَةِ فَمَا الْكَلاَلَةُ قَالَ " تُجْزِيكَ آيَةُ الصَّيْفِ " . فَقُلْتُ لأَبِي إِسْحَاقَ هُوَ مَنْ مَاتَ وَلَمْ يَدَعْ وَلَدًا وَلاَ وَالِدًا قَالَ كَذَلِكَ ظَنُّوا أَنَّهُ كَذَلِكَ .
