Hadith 656 Part A

I also sat alone with him, so he said: 0, son of my brother, I heard the Messenger of Allah (ﷺ) say: He who observed the 'Isha' prayer in congregation, it was as if he prayed up to midnight, and he who prayed the morning prayer in congregation, it was as if he prayed the whole night.
