Sahih Muslim , Book 4, Hadith 1919 (USC-MSA) ⓘ

'Abdullah b. 'Umar, while describing the Nafl prayer of the Messenger of Allah, said: He did not observe (Nafl) prayer after Jumu'a till he went back and observed two rak'ahs in his house. Yahya said: I guess that I uttered these words (before Imam Malik) that he of course observed (them).

وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ وَصَفَ تَطَوُّعَ صَلاَةِ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ فَكَانَ لاَ يُصَلِّي بَعْدَ الْجُمُعَةِ حَتَّى يَنْصَرِفَ فَيُصَلِّي رَكْعَتَيْنِ فِي بَيْتِهِ ‏.‏ قَالَ يَحْيَى أَظُنُّنِي قَرَأْتُ فَيُصَلِّي أَوْ أَلْبَتَّةَ ‏.‏
