If One Forgets to Perform Tashahhud
Issue No.987- If a person forgets to perform tashahhud, and rises and remembers before rukū‘, he should sit down and recite it, and then stand up again and recite the tasbīḥāt arbaʿah again. But if he remembers this in rukū‘ or thereafter, the prayer is correct and it is not necessary for him to return. However, as a recommended precaution, after prayer he should perform the qaḍā of tashahhud and perform sajdah al-sahw for the forgotten tashahhud.
