What is the ruling on the first adhan on Friday?

Question:
The first adhan for Jumu'ah: its wisdom has now passed, so is it considered a religious innovation?

Answer:
It is not a religious innovation, and the wisdom has not passed. Whoever says this has erred. If the first of the Companions of the Prophet (peace and blessings be upon him) could be occupied and might not pay attention to it, how much more so is our condition, you who are present now? Are we more attentive to worship than they were, and more mindful of preserving worship than they were? No, they were more mindful than us and better than us. If Uthman, the Rightly Guided Caliph, did it to serve as a reminder, then those after the Companions are in greater need of a reminder, more occupied, and more heedless. So the need has not passed. It is a reminder that the day is Jumu'ah, so that the believer prepares and hastens to head to the mosques.
The Muslims have continued with it from the time of the Rightly Guided Caliph Uthman until our day in most cities and eras, and it is rare to find a country or state that has abandoned it.
