O Abu Jahl b. Hisham, O Umayya b. Khalaf, O Utba b. Rab'ila, O Shaiba b. Rabi'a, have you not found what your Lord had promised with you to be correct? As for me, I have found the promises of my Lord to be (perfectly) correct. Umar listened to the words of Allah's Apostle (ﷺ) and said: Allah's Messenger, how do they listen and respond to you? They are dead and their bodies have decayed. Thereupon he (the Holy Prophet) said: By Him in Whose Hand is my life, what I am saying to them, even you cannot hear more distinctly than they, but they lack the power to reply. Then'he commanded that they should be buried in the well of Badr.
Sahih Muslim Book 53, Hadith 92
“The Messenger of Allah (ﷺ)
offered prayer, and I am not sure whether he did something extra or
omitted something. He asked, and we told him, so he turned to face the
Qiblah and prostrated twice, then he said the Salam. Then he turned
to face us and said: ‘If any new command has been revealed
concerning the prayer, I would certainly have told you. But I am only
human and I forget and you forget. If I forget, then remind me. And
if anyone of you is uncertain about the prayer, let him do what is
closest to what is correct, then complete the prayer, say the Salam
and prostrate twice.”
Sunan Ibn Majah Book 5, Hadith 409
