Mishkat al-Masabih 29 Excellent Qualities and Description of the Prophet كتاب الفضائل والشمائل 70

وَعَنْهُ أَنَّ امْرَأَةً كَانَتْ فِي عَقْلِهَا شَيْءٌ فَقَالَت: يَا رَسُول الله إِنِّي لِي إِلَيْكَ حَاجَّةً فَقَالَ: «يَا أُمَّ فُلَانٍ انْظُرِي أَيَّ السِّكَكِ شِئْتِ حَتَّى أَقْضِيَ لَكِ حَاجَتَكِ» فَخَلَا مَعَهَا فِي بَعْضِ الطُّرُقِ حَتَّى فرغت من حَاجَتهَا. رَوَاهُ مُسلم

He told that a woman whose mind was affected said, “Messenger of God, I want something from you[*].” He replied, “Mother of so and so, consider which of the streets you wish so that I may accomplish what you want.” He then went alone with her into a road till she got all she wanted. *Presumably meaning that she wished to speak to him privately about something. Muslim transmitted it.
