مُوَطَّأُ مَالِكٍ
Muwatta Malik 280
Tahajjud
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ قَالَ كَانَ عُبَادَةُ بْنُ الصَّامِتِ يَؤُمُّ قَوْمًا فَخَرَجَ يَوْمًا إِلَى الصُّبْحِ فَأَقَامَ الْمُؤَذِّنُ صَلاَةَ الصُّبْحِ فَأَسْكَتَهُ عُبَادَةُ حَتَّى أَوْتَرَ ثُمَّ صَلَّى بِهِمُ الصُّبْحَ .
Yahya related to me from Malik that Yahya ibn Said said, ''Ubada ibn as-Samit used to lead the people in prayer. One day he came out for subh and the muadhdhin began to give the iqama for the subh prayer Ubada silenced him, prayed witr and then led them in subh."
