Chapter 2: Watching the Night in Prayer
Muwatta Malik 254
Yahya related to me from Malik that Yazid ibn Ruman said, "The people used to watch the night in prayer during Ramadan for twenty- three Rak'ahs in the time of Umar ibn al-Khattab."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَزِيدَ بْنِ رُومَانَ، أَنَّهُ قَالَ كَانَ النَّاسُ يَقُومُونَ فِي زَمَانِ عُمَرَ بْنِ الْخَطَّابِ فِي رَمَضَانَ بِثَلاَثٍ وَعِشْرِينَ رَكْعَةً .
