Hi Clive
I made two mistakes in my question posted earlier. Please see amended version below.
Mr. Farhan Danish S/O Mr. Muhammad Sadiq. I believe Farhan Danish S/O Mr. Muhammad Sadiq is the name of a Malay. If I'm correct, the name should be written as follows:
Farhan Danish s/o Mr. Muhammad Sadiq
You're correct; s/o stands for son of. However, s/o is not written in full as s/o is part of the name.
