The word(s) "inwardly" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Do you not see that Allah has made what is in the heavens and what is in the earth subservient to you, and made complete to you His favors outwardly and inwardly? And among men is he who disputes in respect of Allah though having no knowledge nor guidance, nor a book giving light.

(2) And warn them of the day that draws near, when hearts shall rise up to the throats, grieving inwardly; the unjust shall not have any compassionate friend nor any intercessor who should be obeyed.
