The ruling on letting the hands hang down during standing in prayer

The second question in the letter from our brother Sabri al-Jaburi from Iraq. He asks: Is it permissible to let the hands hang down during prayer, or should one clasp them? Which is more correct? Please inform us; may Allah reward you.
Answer: Clasping the hands is the sunnah (recommended practice). This means placing the right hand over the left hand on the chest. This is the sunnah and it is the best. If one lets his hands hang down at his sides, his prayer is valid, but it is disliked (makruh). The best, and the sunnah, is to place the right hand over the left, on the left palm, wrist, and forearm, as established in the authentic hadith from Wa'il ibn Hujr (may Allah be pleased with him) who said: .
And in Sahih al-Bukhari, may Allah have mercy on him, from Abu Hazim from Sahl ibn Sa'd (may Allah be pleased with him), he said: Abu Hazim said: I do not know it except that he traces it—meaning he attributes it—to the Prophet (peace and blessings be upon him). This indicates that placing the right hand over the left on the chest during prayer is the sunnah and the best.
Several reports have come regarding this from the Prophet (peace and blessings be upon him). Yes.
