The auspicious arrival of our beloved Prophet is also above all happiness. Because we know very well that our beloved Prophet is a mercy for the entire creation. Just as God created the moon, the sun, light, and wind for all people, so He sent the beloved Prophet for all states, for all nations, for the entire creation.
So the auspicious arrival of this beloved Prophet on earth is actually a matter of great happiness. And it is not possible to explain how great happiness it is. As an example, we usually celebrate two Eids a lot. One is the Eid of Ramadan and the other is the Eid of Sacrifice.
But both of these would not have come if it were not for the auspicious arrival of our beloved Prophet. That is why the main Eid of both of those Eids is Eid-e-Azam. Or the day of the auspicious arrival of our beloved Prophet. This day is celebrated very beautifully and magnificently by the followers of the beloved Prophet.
