صَدْرهُۥ

Appears 2 times in the Quran. (Root: صدر)
  1. Therefore (for) whomsoever Allah intends that He would guide him aright, He expands his breast for Islam, and (for) whomsoever He intends that He should cause him to err, He makes his breast strait and narrow as though he were ascending upwards; thus does Allah lay uncleanness on those who do not believe.

  2. What! is he whose heart Allah has opened for Islam so that he is in a light from his Lord (like the hard-hearted)? Nay, woe to those whose hearts are hard against the remembrance of Allah; those are in clear error.
