The Messenger of Allah ﷺ stood at night to pray, and a woman was praying along with his prayer. When he became aware of her, he turned to her and said, "Lie down if you wish."She replied, "I find myself energetic for it."He said, "You are not like me. The delight of my eye has been placed in prayer."
أن رسول الله ﷺ قام من الليل، وامرأة تصلي بصلاته، فلما أحس التفت إليها، فقال لها: اضطجعي إن شئت. قال: إني أجد نشاطا، قال: إنك لست مثلي، إنما جعل قرة عيني في الصلاة.

Ibn Nasr Marwazi narrated it in Tazim Qadr Salah (321) from Yahya bin Uthman, who said, "Hiqal narrated to us, from Uzai, from Ishaq bin Abdullah bin Abu Talha, from Anas," and he related it. Tabarani also reported it through this same route, saying, "No one narrated it from Uzai except Hiqal, and Yahya alone transmitted it."Diya Maqdisi said in Mukhtarah (4/367), after reporting it through another route from Amr bin Hashim, meaning Bayruti, "Hiqal bin Ziyad narrated to me with his chain," "Yahya was not alone in narrating it, for Amr also narrated it from him, as we mentioned before." End of quote.I say, its chain is hasan because of Yahya bin Uthman, for his hadith is hasan. It has also been narrated as mursal through a route other than that of Hiqal bin Ziyad, but the connected version is closer to being correct. The woman who was praying behind him was one of his wives ﷺ.
