walaikum musalam. If you tell what your resources say e.t.c it will cause further problems. Your job as a muslim is to use wisdom (hikmat) I will relate the event of shaykh zulfiqar naqshbandi (db), which I heard from another alim. I will try to make it as brief as possible so that you understand how explaining difference of opinion should be dealt. A woman called moulana zulfiqar Sahib (db), Woman : "I hope you do know arabic" Moulana sahib : "Yes I do" Woman : "I want to ask, why do you not recite surah fatiha behind the imam? when prophet (saw) said “There is no prayer for the one who does not recite the Opening of the Book. here moulana now knew that this woman does not understand. Moulana Sahib : " I hope you do know arabic?" Woman : "Yes I do, I am an arab" Moulana Sahib : "I want to ask are you married?" Woman : "Yes I am" Moulana Sahib : "I want to ask have you ever in your time of marriage missed a prayer (salah)? Woman : "Yes I have" Moulana Sahib : "Then your marriage is not valid, as there is hadith that if you miss salah you become kaffir" Woman : "No No.. the meaning of this hadith is different" Moulana Sahib : "This is the same matter with surah fatiha" Then the woman understood what is difference of opinion and was happy with the reply. So this is how a person should use wisdom. If you bring resources, and say "your wrong, no like that .e.t.c." This will just cause further problem, so there is no point in doing this. I hope you understood what I mean.
