Can the Forgetfulness Prostration Be Done in Every Prayer Just to Be Sure it is Valid?
Hanafi Fiqh
Answered by Shaykh Faraz Rabbani
Question
Can the sujud al-sahw be done in every prayer to ensure it is valid?
Answer
It would be prohibitively disliked, sinful, and a reprehensible innovation to perform the Sujud al-Sahw for every prayer without need. Forgetfulness prostrations are only required when one forgetfully leaves a necessary (wajib) action in prayer. It is not required nor permitted for any other action. [Shurunbulali, Nur al-Idah]
You should strive to learn the necessary (wajib) elements of prayer. Any reliable manual of Hanafi fiqh will list these for you.
Also another basic assumption is that actions are valid and sound until proven otherwise.
Note that there is a difference between leaving an obligatory (fard) action in prayer and leaving a necessary (wajib) action – the former invalidates prayer; the latter renders it deficient (though valid).
Past prayers in which wajib actions were omitted do not have to be repeated. It is obligatory to make up prayers in which obligatory (fard) actions–conditions or integrals–of the prayer were omitted. If this is the case, you should how many prayers you have to make up and set a consistent and sustainable schedule of making up the prayers.
And Allah alone gives success.
