Praise be to Allaah.
One should think positively of a Muslim and assume that he
is good and innocent so long as there is no reason for doubt and
suspicion, because Allah says (interpretation of the meaning):
“O you who believe! Avoid much suspicion; indeed some
suspicions are sins. And spy not…”
This Qur’aanic etiquette is one of the means of attaining
happiness and peace of mind, because thinking badly of people leads one to
seek out their faults and may lead to spying or doing something like what
you did, which was a mistake because it may make the wife dare to speak to
men about private matters, as you mentioned.
With regard to talking to her under a different name, it is
not a sin in and of itself. But we should speak about its motive and what

righteousness and keeping away from evil.
Even more important than all of that is not being away from
her for a long time for the purpose of amassing money; rather you should
keep your journeys as short as possible, even if that results in more
expenses or reduces your earnings. Being keen to take care of your wife and
keep her chaste and give her her rights is more important and more
