Assalam Alaikum:
This post dates me back to more than 1.5 decade when I for the first time listened an Adhan just from proximity to a Masjid. It was month of Ramadan and time for Iftar. My Anti-Muslim heart melted. I was in a state of sedation like never felt before. The voice of Adhan seemed to rise from the Masjid to heavens. Masha-Allah. That time I felt intense tranquility and immense peace.
And still any clarifications required to evident that Islam is Deen of Allah?. No certainly not. How reverts are guided to Islam by just listening to Adhan,Alhamdulillah,Alhamdulillah and Alhamdulillah.
Regards.
