Please Pray for My Beloved Father

Assalamualaikum warahmatullahi wabarakatuh. My father just returned to the mercy of Allah on the 18th of last month due to a sudden heart attack. He was the only one I had in this life. Alhamdulillah, I was able to be by his side the whole time. He was such a kind-hearted person. Life in this world will never be the same for me anymore. May Allah help me get through this sorrow. I really ask for prayers from all of you. May Allah place him in the highest paradise, Jannatul Firdaus.
