Ali bin Abdul-Rahman reported,

A man was praying beside Ibn Umar and began fidgeting with the pebbles. Ibn Umar said to him, "Do not play with the pebbles, for that is from Satan. Rather, do as the Messenger of Allah ﷺ used to do." He said, "Like this," and Wahib showed us, and Affan described it. He placed his left hand and spread his fingers on his left knee, and placed his right hand on his right knee as though clenching it, and pointed with his index finger.

حدثنا عفان حدثنا وهيب حدثنا مسلم بن أبي مريم

عن علي بن عبد الرحمن المعاوي

أن رجلا صلى إلى جنب ابن عمر فجعل يعبث بالحصى فقال لا تعبث بالحصى فإنه من الشيطان ولكن اصنع كما كان رسول الله ﷺ يصنع قال هكذا وأرانا وهيب وصفه عفان وضع يده اليسرى وبسط أصابعه على ركبته اليسرى ووضع يده اليمنى على ركبته اليمنى وكأنه عقد وأشار بالسبابة
