The Quran Gives Guidance in this World and the Hereafter – Dr Zakir Naik

Respected Dr. Zakir Naik,
Assalamu Alaikum.
I am Nadim Hosen, a Class 10 high school student from Jamalpur, Bangladesh. I am a regular viewer of your programs and have a specific question regarding the pursuit of knowledge for the sake of Islam.
My Question:
If a person starts learning a foreign language, specifically English, with the primary intention of performing Dawah (conveying the message of Islam) more effectively to the world, how does Sharia view this effort? Furthermore, if that person passes away while still in the process of learning the language for this noble cause, what would be their status or reward in the eyes of Allah (SWT)?
I would be extremely grateful if you could provide some guidance on this matter in your upcoming Q&A session.
JazakAllah Khair.
Best regards,
Nadim Hosen
