Alqama reported,

Abdullah reported that the Prophet ﷺ led the prayer. Ibrahim said, "I do not know whether he added or omitted something."When he gave the salam, it was said to him, "Messenger of Allah, has something new occurred in the prayer?"He asked, "What is that?"They said, "You prayed such and such."So he folded his legs, faced the qiblah, performed two prostrations, and then gave the salam. When he turned his face toward us, he said, "If something new had occurred in the prayer, I would have informed you of it. But I am only a human being like you. I forget as you forget. So when I forget, remind me. And if any of you is uncertain about his prayer, let him seek what is correct, complete the prayer accordingly, then give the salam, then perform two prostrations."

Sahih

حدثنا عثمان قال حدثنا جرير عن منصور عن إبراهيم

عن علقمة قال

قال عبد الله صلى النبي ﷺ قال إبراهيم لا أدري زاد أو نقص فلما سلم قيل له يا رسول الله أحدث في الصلاة شيء قال وما ذاك قالوا صليت كذا وكذا فثنى رجليه واستقبل القبلة وسجد سجدتين ثم سلم فلما أقبل علينا بوجهه قال إنه لو حدث في الصلاة شيء لنبأتكم به ولكن إنما أنا بشر مثلكم أنسى كما تنسون فإذا نسيت فذكروني وإذا شك أحدكم في صلاته فليتحر الصواب فليتم عليه ثم ليسلم ثم يسجد سجدتين
