Qāḍī ʿIyāḍ said, “There is unanimous agreement among the scholars that if a person performs the prostration—whether after the salām or before it, whether the cause is an addition or a deficiency—it is sufficient and his prayer is not invalid; their divergence concerns only which option is preferable.”

The compiler remarks, “This is a sound position: it is permissible to act upon all of these authentic Sunnahs. Allah knows best.”
