'Uthman b. 'Affan (narrated the mosque after evening prayer and sat alone. 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.
Sahih Muslim Book 5, Hadith 324 Next Hadith → He who prayed the morning prayer (in congregation) he is in fact under the protection of Allah. And it can never happen that Allah should demand anything from you in connection with the protection (that He guarantees) and one should not get it. He would then throw him in the fire of Hell.
