“Certainly you have in the Messenger of Allah an excellent example for him who hopes in Allah and the last day and remembers Allah much.” (Qur’an 33:21)
﷽
Malik ibn al-Huwayrith reported: The Prophet, (saw), said, “Pray as you have seen me praying. When the time of prayer arrives, let one of you announce the call to prayer for you and then let the older of you leader the prayer.” Source: (https://sunnah.com/bukhari:631)
Salafi Shaykh Assim Al-Hakeem repeated a whopper of a lie about Imam Malik (and the way he performed prayer). He has yet to publically correct his position. He has also yet to provide us any evidence of his claims.
This is the article with his previous (incorrect) position parroting the mistake of Salafi preacher, Bilal Philips.
Shaykh Assim al-Hakeem metions about praying with the arms to the side.
Shaykh Assim Al-Hakeem says: “The, the famous dispute among Muslims rather to put my hand over the belly, on the chest or under the belly. Akhi if you pray, Al hamdulillah! Five times a day on time in the masjid it’s o.k where you want to put your hand. There are a hadith that stated, hadith Wail Ibn Hujr (May Allah be pleased with him) that the prophet used to put the right over the left on the chest. Now there are other hadiths that state that he used to put it, them under the navel or on his stomach. Wherever you feel good about do it! It is a Sunnah, SO EVEN IF YOU DON’T PUT YOUR HANDS ALTOGETHER, IF YOU JUST PUT THEM ON YOUR SIDE YOUR PRAYER IS VALID. YOUR PRAYER IS CORRECT. But, you should try your level best to follow the most authentic hadith and I, uh, uh, uh believe that the most authentic hadith which Al Albani (May Allah have mercy on him) also authenticated states that you put them on the chest.”
