Sunan Abi Dawud

Narrated 'Abd Allah bin 'Amr: The Messenger of Allah (ﷺ) was asked about lailat al-qadr and I was hearing: He said: It is during the whole of Ramadan. Abu Dawud said: Sufyan and Shu'bah narrated this tradition from Abu Ishaq as a statement of Ibn 'Umar himself, they did not transmit it as a saying of the Prophet (ﷺ)
