Musannaf Ibn Abi Shaybah 3371 — Whether the later Isha is hastened

Ibn Labibah said: Sayyiduna Abu Hurayrah (may Allah be pleased with him) said to me: Offer the Isha prayer when the twilight has disappeared and the night has grown dark, from then until a third of the night. And the sooner you pray it after the whiteness of the horizon has gone, the better.
