1. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan from Hammad ibn ‘Isa from Rib‘i ibn ‘Abd Allah from Muhammad ibn Muslim who has said the following: “One of the two Imam, ‘Alayhim al-Salam, has said, ’Allah has made Ruku‘ (bowing down on one’s knees) and Sujud (prostrations) obligatory. Recitation is Sunnah. Whoever omits recitation willfully performs Salah (prayer) again. Whoever forgets recitation his Salah (prayer) is complete and he is not obligated for anything in this matter.’”

Translation: Muhammad Sarwar — attributed by Thaqalayn·The Arabic above is the original.

He (the Imam) said, ‘If he has not yet reached Ruku‘ position, he recites it again.’”

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from Yunus ibn Ya‘qub from Mansur ibn Hazim who has said the following: “I once said to abu ‘Abd Allah (a.s.), ‘I performed the obligatory Salah (prayer) but forgot the recitation in all of my Salah (prayer). He (the Imam) asked, ‘Did you complete Ruku‘ (bowing down on one’s knees) and Sujud (prostrations)?’ I replied, ‘Yes, I did so.’ He (the Imam) said, ‘Your Salah (prayer) is complete if it was because of forgetfulness.’”
