Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: I found most of the hadiths of the Messenger of Allah (peace and blessings be upon him) in this neighborhood of the Ansar. By Allah, I would go to one of their men and it would be said that he is sleeping. If I wished, he could have been awakened for me, but I would let him sleep until he came out by himself, and in this way I would learn the hadith from him properly.
