Abu Ishaq al-Sabay'ai' أبو إسحاق السبيعي عمرو بن عبد الله · The Book of the Sunnah

"The Messenger of Allah (ﷺ) led us in Fajr (morning) prayer, then he turned to us and delivered an eloquent speech". And he mentioned something similar (as no.43)

"The Messenger of Allah (ﷺ) said: 'None of you truly believes until he loves for his brother" or he said "for his neighbor, what he loves for himself."
