Mishkat al-Masabih 13 Marriage كتاب النكاح 174

وَعَنْ طَلْقِ بْنِ عَلِيٍّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا الرَّجُلُ دَعَا زَوْجَتَهُ لِحَاجَتِهِ فَلْتَأْتِهِ وَإِنْ كَانَتْ عَلَى التَّنور» . رَوَاهُ التِّرْمِذِيّ

Talq b. ‘Ali reported God’s Messenger as saying, “When a man calls his wife to satisfy his desire she must go to him even if she is occupied at the oven.” Tirmidhi transmitted it.
