حدثنا سهل بن أبي سهل ومحمد بن يحيى قالا حدثنا أبو الوليد حدثنا حماد عن علي بن زيد عن سلمة بن محمد بن عمار بن ياسر
أن رسول الله ﷺ قال من الفطرة المضمضة والاستنشاق والسواك وقص الشارب وتقليم الأظفار ونتف الإبط والاستحداد وغسل البراجم والانتضاح والاختتان حدثنا جعفر بن أحمد بن عمر حدثنا عفان بن مسلم حدثنا حماد بن سلمة عن علي بن زيد مثله
