Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا ابْنُ الْعَلاَءِ، عَنْ وَكِيعٍ، عَنْ سُفْيَانَ، عَنْ سُهَيْلٍ، نَحْوَهُ قَالَ " فِي الصَّلاَةِ فَلْيَكْظِمْ مَا اسْتَطَاعَ " .
The tradition mentioned above has also been transmitted in a similar way by Suhail through a different chain of narrators. This version has; “during prayer, so he should hold as far as possible”.
