Fathwa, - A brother recently said to me "You are lying", but I was not lying. Have I been wrong

Question:
A brother recently said to me "You are lying", but I was not lying.
Have I been wronged? Or is this solely between him and Allah?
Answer:
In the Name of Allah, Most Merciful and Compassionate
May Allah's peace and blessings be upon His Messenger Muhammad, his
folk, companions, and followers
Walaikum assalam wa rahmatullah,
This would really depend on the situation and circumstances. He may
have reason to have thought you were in error; or he may have made an
error in judgment; or he may simply be wrong. In any case, we don't
impute ill-intent in the actions of other, even when these are against
us. Rather, we try to understand their actions in the best light, and
to be fair. Allah Most High says,
"O you who believe! Be steadfast witnesses for Allah in fairness, and
let not enmity of any people lead you not to act justly. Deal justly,
that is nearer to piety. Be pious of Allah. Indeed, Allah is Informed
of what you do." [Qur'an, 5.8]
In terms of dealing with the brother in question, it would be best to
sit down and discuss the matter with him, in a spirit of brotherhood,
and in order to come to understanding--not to argue your point and
seek "your" rights, but rather to mend relations and move on. Allah
Most High says,
"The believers are but brethren, so mend relationships between your
brethren. Be pious of Allah, that you may obtain mercy." [Qur'an,
49.10]
And Allah alone gives success.
