The Prophet ﷺ forbade a man to pray with his hands on his hips.
حدثنا أبو كريب حدثنا أبو أسامة عن هشام بن حسان عن محمد بن سيرين
أن النبي ﷺ نهى أن يصلي الرجل مختصرا
Agreed upon by both. Muslim also related it in the Book of Mosques, chapter on the disapproval of standing with hands on hips during prayer, hadith no. 545, from the hadith of Abu Usama Hammad bin Usama, and Bukhari, hadith no. 1220, from the hadith of Hisham bin Hassan, through him.There is also a version on this subject from Ibn Umar [Abu Dawud, hadith no. 903].
