The Sahabah (may Allah be pleased with them) were the keenest of people to learn about their religion from the Prophet (blessings and peace of Allah be upon him) and to transmit what they learned to the Muslims who came after them. Prayer was foremost among the things that they wanted to learn and transmit, and it was their top priority. In this hadith, Sahl ibn Sa‘d al-Sa‘idi (may Allah be pleased with him) describes how the hands are to be placed when praying. He said: The people were instructed that a man should place his right hand on his left forearm when praying. What is meant by his saying that they were instructed is that the one who instructed them to do this was the Prophet (blessings and peace of Allah be upon him). Hence the Tabi‘i Abu Hazim Salamah ibn Dinar al-A‘raj said: I do not think but that Sahl ibn Sa‘d (may Allah be pleased with him) attributed this to the Prophet (blessings and peace of Allah be upon him). This hadith does not explain precisely where the hand is to be placed on the forearm. But it was narrated from the Prophet (blessings and peace of Allah be upon him) in many reports that he used to place the palm of his right hand on the back of his left hand, wrist and forearm when praying, as is mentioned in the hadith of Wa’il ibn Hujr (may Allah be pleased with him) that was narrated by Abu Dawud. The wrist is the joint between the forearm and the hand. This is what the Sahabah (may Allah be pleased with the m) used to do. This hadith explains where the hands are to be placed when reciting Qur’an whilst standing in prayer..
