What is the ruling on frequent forgetfulness in prayer, and is the prostration of forgetfulness (sujood as-sahw) obligatory with repeated forgetfulness, and is my prayer accepted?

The prostration of forgetfulness (sujud al-sahw) does not compensate for omitting a complete rak'ah (unit of prayer), the final tashahhud (recitation), bowing (ruku'), or prostration (sujud). Rather, one must perform what was omitted, and then prostrate for forgetfulness.
