Arabic hadith text
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 ‏.‏
Translation

Yahya related to me from Malik that Yahya ibn Said said, ''Ubadaibn as-Samit used to lead the people in prayer. One day he came outfor subh and the muadhdhin began to give the iqama for the subh prayerUbada silenced him, prayed witr and then led them in subh."
