What are the pilgrims' mistakes when stoning the Jamarat?

The ritual of Rami al-Jamarat (pelting the pillars) is a great rite ordained for the remembrance of Allah Almighty. It was reported from the Prophet, peace and blessings be upon him, that he pelted Jamarat al-Aqaba with seven pebbles, similar to date stones, uttering "Allahu Akbar" with each pebble.

Among the common mistakes made when pelting the Jamarat are: 1. Believing that the pebbles must be gathered from Muzdalifah, whereas the correct view is that they can be taken from any location. 2. Washing the pebbles, which is an innovation not practiced by the Prophet, peace and blessings be upon him. 3. Believing that the Jamarat are devils, and pelting them with violence and anger. This is a mistaken belief that leads to harming people and using large stones or impermissible items. The correct approach is that the pelting is an act of glorifying Allah, an act of worship to Him, and an adherence to the Sunnah of the Prophet, peace and blessings be upon him, while uttering "Allahu Akbar" with each pebble. 4. Being negligent in ensuring that the pebble falls into the designated basin. The correct approach is to have strong conviction that it has fallen into it. 5. Believing that the pebble must hit the pillar. The correct view is that the pillar is merely a marker, and it suffices for the pebble to fall within the basin. 6. Appointing someone to pelt on behalf of a capable pilgrim. This is a significant error, unless there is a valid excuse preventing the pilgrim from pelting themselves at any time of night or day.
