spirituality

Dear scholars, As-Salamu `alaykum. Could you please shed light on spiritual health in Islam. Also, what are the major diseases that affect the heart and what are the cures if one is affected with these ailments? Jaza kum Allah khayran.

As-salaamualaikum respected Scholar/sMy question is whether a wife is allowed to pledge Ba'yah to a Sheik without the permissions of her husband. My wife would like to pledge Ba'yah to a Sufi Shaykh and I would like to know whether she needs my permission to do so.With kindness Imtiaz
