أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي قَتَادَةُ، عَنْ أَبِي حَسَّانَ، عَنْ عَبِيدَةَ، عَنْ عَلِيٍّ، - رضى الله عنه - عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " شَغَلُونَا عَنِ الصَّلاَةِ الْوُسْطَى حَتَّى غَرَبَتِ الشَّمْسُ " .
