وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «خِيَارُكُمْ أَلْيَنُكُمْ مَنَاكِبَ فِي الصَّلَاة» . رَوَاهُ أَبُو دَاوُد
Ibn ‘Abbas reported God’s Messenger as saying, ‘‘The best of you are those whose shoulders give least annoyance in prayer." Abu Dawud transmitted it.
