As Salaam Alaykum Wa Rahmatullahi Wa Barakatuhu
Prophet Muhammad is our model and example in showing compassion about others' concerns. It was reported that Prophet Muhammad was a good listener. Allah has described his patience in listening to others in the Holy Quran.
And say,
"He is (all) ear." Say, "He listens to what is best for you: he believes in Allah, has faith in the Believers, and is a Mercy to those of you who believe."Surah Tawbah, Ayah 61
Allah has indeed heard (and accepted) the statement of the woman who pleads with thee concerning her husband and carries her complaint (in prayer) to Allah: And Allah (always) hears the arguments between both sides among you: for Allah hears and sees (all things). Surah Mujadilah, Ayah 1
Quran reminds us that in any form of counseling, or private talks, Allah is present and hears what we are saying. (58:7) Quran also teaches us that the private talk in our counseling is to help others to be righteous and to be obedient to Allah. (58:9) Any effort that we make in bringing people together is considered sadaqah, and Allah will reward us for it.
So the Imams will keep it very confidental and they've been trained by this counselling courses. Best advice for you is that you can going to talk the Imam about this and Insha'Allah they will organising for sister of Islam could help your mum to walk on the right of Path.
Insha'Allah
