Du’a for my nephew Sufian

Assalam'alaikum,

I would like to request a du'a and prayer for my late nephew, who passed away yesterday at only 25 years old. His name is Sufian Bin Hassin Hashim. He passed away due to difficulty breathing. His sudden passing had greatly impacted my family.

إِنَّا لِلّهِ وَإِنَّـا إِلَيْهِ رَاجِعونَ 

Oh Allah, forgive our living and our dead, those who are present and those who are absent, our young and our old, our males and our females. O Allah, whomever of us You cause to live, let him live in Islam, and whomever of us You cause to die, let him die in a state of faith.
