Is the new Muslim wife's initial shyness about declaring her Islam for the first time in front of those she knows, followed by the later disappearance of this shyness, considered evidence of a deficiency in her faith in Allah?

The fundamental principle regarding the concealment of faith is that it is a concession for the weak who are unable to outwardly practice their rituals. However, if one manifests their faith with the intention of glorifying the religion despite potential harm, they will be rewarded. Nevertheless, a wife's failure to inform her husband of her conversion to Islam might not be a concealment of faith, but rather a deficiency or weakness. Despite this, one should not be overly strict with new converts to Islam. It is wise for a scholar or preacher to postpone some religious commands for them, out of consideration for their circumstances, as obligations and prohibitions are conditional upon the ability to know and act.
