Aslamo Alykum Warahmatuallah,
Please can you ask Muwlana about the negativity I am feeling, especially when I start reciting one 100 time Tasbhee of walahaulawalaqwatuallah and subahn Allah wabyhamdy subahn Alazeem. Feeling lot of stress and have started pain on the shoulders. Can I continue that reciting or stop it for moments?
It may happen at times. When you feel that, stop that dhikr for a while and make Salawat instead.
