Is it enough for a fiancée that the suitor prays and has good character, or should she insist on her condition that he not bring satellite channels, especially since her age no longer allows for setting conditions?

The questioner is thanked for stipulating religiosity in a suitor, which is a matter that should not be compromised. It is not required that he be a student of knowledge, but rather that he avoids forbidden acts and performs obligatory ones. One should not accept a husband who is negligent in prayer, or allows mixing (of genders), or watches forbidden things. If she stipulates that there should be no corrupting satellite channels in his home, then it is an excellent condition, especially with the availability of purposeful Islamic alternatives. If a girl advances in age, she may accept a righteous husband of good character, even if he has some sins, attempting to guide him towards complete righteousness. This is from the perspective of committing the lesser of two harms, while emphasizing the necessity of choosing someone known for good character and protective jealousy (ghirah), from a good family, and consulting the wise among her family.
