Sunan Abi Dawud, 727
sahih· Al-Albani

The above tradition has been transmitted by ‘Asim b. Kulaib through a different chain of narrators and to the same effect. This version has:

“He then placed his right hand on the back of his left palm and his wrist and forearm.” This also adds: “I then came back afterwards in a season when it was severe cold. I saw the people putting on heavy clothes moving their hands under the clothes (i.e. raised their hands before and after bowing).”

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا زَائِدَةُ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، بِإِسْنَادِهِ وَمَعْنَاهُ قَالَ فِيهِ ثُمَّ وَضَعَ يَدَهُ الْيُمْنَى عَلَى ظَهْرِ كَفِّهِ الْيُسْرَى وَالرُّسْغِ وَالسَّاعِدِ وَقَالَ فِيهِ ثُمَّ جِئْتُ بَعْدَ ذَلِكَ فِي زَمَانٍ فِيهِ بَرْدٌ شَدِيدٌ فَرَأَيْتُ النَّاسَ عَلَيْهِمْ جُلُّ الثِّيَابِ تَحَرَّكُ أَيْدِيهِمْ تَحْتَ الثِّيَابِ ‏.‏
