Moving the Body Forgetfully
Issue No.882- If, while standing for al-fātiḥa and sūrah, a person forgetfully moves his body and feet or inclines towards one side or lean on something, the prayer is not void. However, if it is at the time of takbīrat-ul-iḥrām or qīyām connected to rukū‘, he should, as an obligatory precaution, finish the prayer and then offer it again.
