Sahih al-Bukhari 1175
Narrated Muwarriq:
I asked Ibn `Umar "Do you offer the Duha prayer?" He replied in the negative. I further asked, "Did 
`Umar use to pray it?" He (Ibn `Umar) replied in the negative. I again asked, "Did Abu Bakr use to 
pray it?" He replied in the negative. I again asked, "Did the Prophet (ﷺ) use to pray it?" Ibn `Umar replied, 
"I don't think he did."
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، عَنْ تَوْبَةَ، عَنْ مُوَرِّقٍ، قَالَ قُلْتُ لاِبْنِ عُمَرَ ـ رضى الله عنهما ـ أَتُصَلِّي الضُّحَى قَالَ لاَ‏.‏ قُلْتُ فَعُمَرُ‏.‏ قَالَ لاَ‏.‏ قُلْتُ فَأَبُو بَكْرٍ‏.‏ قَالَ لاَ‏.‏ قُلْتُ فَالنَّبِيُّ صلى الله عليه وسلم قَالَ لاَ إِخَالُهُ‏.‏
