Narrated Anas ibn Malik:

A woman came to the Messenger of Allah ﷺ and said: Messenger of Allah: I have some need with you. He said to her: Mother of so and so, sit in the corner of any street you wish and I shall sit with you. So she sat and the Messenger of Allah ﷺ also sat with her till she fulfilled her need.

The narrator Ibn 'Isa did not mention "till she fulfilled her need." And Kathir said: from Humaid on the authority of Anas.

حَدَّثَنَا مُحَمَّدُ بْنُ عِيسَى بْنِ الطَّبَّاعِ، وَكَثِيرُ بْنُ عُبَيْدٍ، قَالاَ حَدَّثَنَا مَرْوَانُ، - قَالَ ابْنُ عِيسَى قَالَ - حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسٍ، قَالَ جَاءَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ لِي إِلَيْكَ حَاجَةً . فَقَالَ لَهَا
" يَا أُمَّ فُلاَنٍ اجْلِسِي فِي أَىِّ نَوَاحِي السِّكَكِ شِئْتِ حَتَّى أَجْلِسَ إِلَيْكِ " . قَالَ فَجَلَسَتْ فَجَلَسَ النَّبِيُّ ﷺ إِلَيْهَا حَتَّى قَضَتْ حَاجَتَهَا . وَلَمْ يَذْكُرِ ابْنُ عِيسَى حَتَّى قَضَتْ حَاجَتَهَا . وَقَالَ كَثِيرٌ عَنْ حُمَيْدٍ عَنْ أَنَسٍ .
