Sayyidina Hudhaifa ibn Yaman (RA) reported that the Prophet (SAW) said, “By Him Who has my soul in His hand, you will keep enjoining that which is right, and forbidding that which is evil or, it will be very quick that Allah will send on you a punishment. You will pray, but you will not be heard.”
[Abu Dawud 4338, Ibn Majah 4005]
