Narrator:Abdullah ibn Arqam
حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ الأَرْقَمِ، قَالَ أُقِيمَتِ الصَّلاَةُ فَأَخَذَ بِيَدِ رَجُلٍ فَقَدَّمَهُ وَكَانَ إِمَامَ قَوْمِهِ وَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ
" إِذَا أُقِيمَتِ الصَّلاَةُ وَوَجَدَ أَحَدُكُمُ الْخَلاَءَ فَلْيَبْدَأْ بِالْخَلاَءِ "
