When the Prophet spoke about the strong believer, he didn’t just refer to pyhysical or material strength; rather he primarily meant moral and spiritual strength.

 

So those in paradise mostly are not the rich and famous; rather they are firm believers although they are weak in material status.

 

The prophet is told in the Qur’an to keep the company of the believers such as Bilal, Suhyab, Salman, `Ammar, etc. who were materially week but spiritually and morally strong.

 

 

When some of the companies laughed at the slender legs of Ibn Mas`ud as he climbed a tree, the Prophet asked them: Are you laughing at his legs; they are weightier in the sight of Allah than the mountain of Uhud!

 

So, we must never try to project our subjective meaning onto the sacred texts (i.e., the Qur’an and Hadith).

 

Almighty Allah knows best.
