'Allah Ho Ya Rehman (God is Great and Merciful)' is a 'hamd', i.e. a song in praise of God.

Taken from the Rizwan-Muazzam Qawwali album 'Sacrifice to Love': https://realworldrecords.com/releases/sacrifice-to-love/

"You are great and wonderful. You are the God of the whole universe. God, you are kind and merciful and for that I love you very much. You have control over life and death.You are the only one and there is no other God but you. You are in everything and everywhere, and everybody is in search of you. You own the whole universe. This land and sky, everything is yours. Anybody who remembers you and recites your name wholeheartedly gains great respect in the world. Like Bilal, who became Muslim and gained unique status just because he accepted your message and followed it. The day that Bilal does not say Azan for the early morning prayer, daylight does not appear. Seeing these things makes one believe in your existence."
