She had prayed toward both qiblahs with the Messenger of Allah ﷺ. She said, "The Messenger of Allah ﷺ came in to me and said to me, 'Apply henna. One of you leaves off the henna until her hand becomes like the hand of a man.'"She said, "I never gave up applying henna until I met Allah ." Indeed, she would still apply henna even when she was eighty years old.
قال حدثنا يزيد بن هارون قال أخبرنا محمد بن إسحاق عن ضمرة بن سعيد عن جدته
وقد كانت صلت القبلتين مع رسول الله ﷺ قالت دخل علي رسول الله ﷺ فقال لي اختضبي تترك إحداكن الخضاب حتى تكون يدها كيد الرجل قالت فما تركت الخضاب حتى لقيت الله عز وجل وإن كانت لتختضب وإنها لابنة ثمانين
Its isnad is daif, because the grandmother of Ibn Damrah is unknown, and Haythami likewise judged it daif in 5/171. However, it is supported by many hadiths that Haythami mentioned, some of which strengthen others, and the best of these hadiths in terms of condition is what Bazzar narrated from Ibn Abbas, that a woman came to the Prophet ﷺ to pledge allegiance to him, but she had not applied henna, so he did not accept her pledge until she had applied henna. Bazzar narrated it, and Layth bin Abu Salim is in the chain, who was a mudallis, Majma 5/172.
