وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي لَبِيدٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
" لاَ تَغْلِبَنَّكُمُ الأَعْرَابُ عَلَى اسْمِ صَلاَتِكُمُ الْعِشَاءِ فَإِنَّهَا فِي كِتَابِ اللَّهِ الْعِشَاءُ وَإِنَّهَا تُعْتِمُ بِحِلاَبِ الإِبِلِ " .
