It was narrated that Abu Hurairah said:
The Messenger of Allah (ﷺ) promised us that we would invade India. If I live to see that, I will sacrifice myself and my wealth. If I am killed, I will be one of the best of the martyrs, and if I come back, I will be Abu Hurairah Al-Muharrar. [1] [1] Al-Muharrar: The one freed (from the Fire).
