Shaykh Ibn Uthaymeen mentioned two mistakes in prayer that have no origin for it:
- Those who start the prayer, Say Allah Akbar and then drop their hands to the side and then raise them back up and put their right on their left.
- The second one is while the person is standing he grabs his elbow whilst the Sunnah is to place it on the elbow and not grab.
