Mishkat al-Masabih 1321
Muwarriq al-Ijli said:
I asked Ibn ‘Umar whether he prayed in the forenoon and he said he did not. I asked whether ‘Umar did and he said he did not. I asked whether Abu Bakr did and he said he did not. I asked whether the Prophet did and he said, “I don’t think so.” 

Bukhari transmitted it.
وَعَنْ مُوَرِّقٍ الْعِجْلِيِّ قَالَ: قُلْتُ لِابْنِ عُمَرَ: تُصَلِّي الضُّحَى؟ قَالَ: لَا. قُلْتُ: فَعُمَرُ؟ قَالَ: لَا. قُلْتُ: فَأَبُو بَكْرٍ؟ قَالَ: لَا. قُلْتُ: فَالنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ؟ قَالَ: لَا إخَاله. رَوَاهُ البُخَارِيّ
