Question:
If during recitation in prayer, a verse or a word is mistakenly omitted, does this necessitate Sujūd al-Sahw (the prostration of forgetfulness)?
Answer:
Al-ḥamdu lillāh, waṣ-ṣalātu wa-s-salāmu ʿalā Rasūlillāh, ammā baʿd:
If a person, while reciting in prayer, forgets a verse, or a word from a verse is mistakenly left out, then Sujūd al-Sahw does not become obligatory in such a case.
✿ Sujūd al-Sahw is only required when there is an addition or omission in the actual acts of prayer.
✿ Simply forgetting a word or verse during recitation does not necessitate Sujūd al-Sahw, as long as it does not affect the essential pillars (arkān) or obligations (wājibāt) of the prayer.
✿ Therefore, merely leaving out a verse or a word in recitation does not make Sujūd al-Sahw obligatory.
