Jami` at-Tirmidhi 2619
حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا أَسْبَاطُ بْنُ مُحَمَّدٍ، عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ نَحْوَهُ وَقَالَ " بَيْنَ الْعَبْدِ وَبَيْنَ الشِّرْكِ أَوِ الْكُفْرِ تَرْكُ الصَّلاَةِ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَأَبُو سُفْيَانَ اسْمُهُ طَلْحَةُ بْنُ نَافِعٍ .
