One of the duties of the awaiting people is to wait for his reappearance and to prepare themselves for that enormous event. God in the Quran accounts worshiping as a goal of human creation.”
The Prophet says while interpreting this verse in the Quran that the best worship is expectation for Imam Mahdi’s Reappearance
Mekyal al-Makarem, volume 2
A reminder:
We should examine ourselves to see how much we are really waiting for Imam Mahdi.
