Be mindful during your prayers so you don't forget any part of it . Make sure you follow all steps correctly . If you make a mistake or forget something , repent by doing extra prostration afterwards . Follow what Prophet Muhammad PBUH did when he forgot to sit down after two rak’ahs of Zuhr .

This hadith is about making up for forgotten sitting in prayer. It was narrated from 'Abdur-Rahman Al A'raj that Abdullah bin Buhainah told him that the Messenger of Allah stood up following two rak'ahs of Zuhr and did not sit down for tashahhud. When he finished the prayer he prostrated twice, saying Takbir for each prostration while he was sitting before he said the taslim, and the people prostrated with him. This is a reminder to us to be mindful during our prayers so we don't forget any part of it. We should also remember that if we do forget something or make a mistake during our prayers, we can make it up by doing extra prostration afterwards as taught by Prophet Muhammad PBUH himself.
