Musnad Ahmad 2294
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
Ibn 'Abbas (رضي الله عنه) said: Someone came to me in a dream during Ramadan, and it was said to me: Tonight is Lailatal-Qadr. So I got up, although I was drowsy, and I came to the Messenger of Allah (ﷺ) and found him praying. I looked to see what night that was, and it was the night of the twenty-third.
