What is the ruling on not saying "Subhanallah" (Tasbeeh) during the two prostrations of forgetfulness (Sajdat al-Sahw)?

The remembrance (dhikr) prescribed for the prostration of forgetfulness (sujud al-sahw) is the same as that prescribed for any prostration in the regular prayer. If one intentionally or forgetfully omits this glorification (tasbih), their prayer is still valid. For the majority of scholars, the tasbih in the prostration of prayer is a Sunnah (recommended act) and not obligatory, and its omission does not invalidate the prayer. If one omits it forgetfully, they are not required to perform the prostration of forgetfulness, and their prayer is valid.
