Prayer
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ إِذَا سُئِلَ هَلْ يَقْرَأُ أَحَدٌ خَلْفَ الإِمَامِ قَالَ إِذَا صَلَّى أَحَدُكُمْ خَلْفَ الإِمَامِ فَحَسْبُهُ قِرَاءَةُ الإِمَامِ وَإِذَا صَلَّى وَحْدَهُ فَلْيَقْرَأْ . قَالَ وَكَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ لاَ يَقْرَأُ خَلْفَ الإِمَامِ . قَالَ يَحْيَى سَمِعْتُ مَالِكًا يَقُولُ الأَمْرُ عِنْدَنَا أَنْ يَقْرَأَ الرَّجُلُ وَرَاءَ الإِمَامِ فِيمَا لاَ يَجْهَرُ فِيهِ الإِمَامُ بِالْقِرَاءَةِ وَيَتْرُكُ الْقِرَاءَةَ فِيمَا يَجْهَرُ فِيهِ الإِمَامُ بِالْقِرَاءَةِ .
Yahya related to me from Malik from Nafi that Abdullah ibn Umar,
when asked if anyone should recite behind an imam, said, "When you
pray behind an imam then the recitation of the imam is enough for you
and when you pray on your own you must recite." Nafi added, "Abdullah
ibn 'Umar used not to recite behind the imam."
Yahya said
that he heard Malik say, "The position with us is that aman recites
behind the imam when the imam does not recite aloud and he refrains
from reciting when the imam recites aloud."
