I was with Ibn Umar along with another man, when he called over a third man. He then said, "Step back a little, for the Messenger of Allah ﷺ forbade two people from conversing privately to the exclusion of a third."
حدثنا عبد الرحمن حدثنا سفيان
كنت مع ابن عمر أنا ورجل آخر فدعا رجلا آخر ثم قال استرخيا فإن رسول الله ﷺ نهى أن ينتجي اثنان دون واحد
