What is the meaning of Muslim name "Talha"?

Answer 1

In this Names site online, the "meaning" is merely a definition:
"a kind of tree."

I know enough Arabic to honestly tell you that this is not enough,
nor is it enough to extrapolate English associations from the word
"tree" and give the word "Talha" qualities based on them...
Just consider the atrocious misunderstandings that have grown from approaching the Quran's Arabic "meanings" in this superficial and erroneous way!
Moral: Any research is best done from Arabic sourcing.

Answer 2

Talha is a boy's name that is a kind of tree. So perhaps taken further, it means close to nature and unwavering.
