Should we use "Jazak Allah khair" instead of "Shookran" or "Thanks"?
I have heard people using the phrase "Jazak Allah khair" at times when it was appropriate to thank others and always wondered if that is something advised to do. But I've also seen some people who emphasize on saying the phrase "Jazakallah Khair" over saying the phrase "Thanks!" with their own reasons.
Anyways, here are my questions
I do understand the logic that it is generally good thing to make dua for fellow Muslims.
However, is there anything in Qur'an, Sunnah and/or in the consensus among Sahaba that saying "Jazak Allah khair" is superior to simply saying "thanks"?
Also, a bonus would be, if you also try to answer can we use the phrase "Thanks" instead of "Jazakallah Khair", in case if the helper is a non Muslim, because he won't be understanding the meaning of the words nor it's importance (if at all I manage to explain it by translating it).
