Abu Dawud Book 2, Hadith Number 906.

Narated By Al-Miswar ibn Yazid al-Maliki : The Apostle of Allah (PBUH) recited – Yahya (sub narrator) said: Sometimes al-Miswar said: I prayed along with the Apostle of Allah (PBUH) and witnessed that he recited – the Qur’an during the prayer and omitted something (i.e. some verses inadvertently) which he did not recite.

A man said to him: Apostle of Allah, you omitted such-and-such verse. The Apostle of Allah (PBUH) said: Why did you not remind me of it?

The narrator Sulayman said in his version: He (the man) said: I thought that it (the verse) was repealed.
