Hadith 2:103
Narrated Abu Hurairah (RA):
Allah's Messenger (ﷺ) forbade keeping one's hands on one's waist while praying. [Agreed upon]. The wording is that of Muslim's. And it's meaning is to put (one's) hands on his waist.
عَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ : { نَهَى رَسُولُ اَللَّهِ - صلى الله عليه وسلم -أَنْ يُصَلِّيَ اَلرَّجُلُ مُخْتَصِرًا } مُتَّفَقٌ عَلَيْهِ , وَاللَّفْظُ لِمُسْلِمٍ وَمَعْنَاهُ : أَنْ يَجْعَلَ يَدَهُ عَلَى خَاصِرَتِهِ
