Q: When I was at my parents house my husband called me and asked me not to come back because according to him "I may not be a Muslim in future". My brother texted him and asked him what religion will he accept now. He replied I don't like any religion. My brother then asked so you are saying there is no god. He said yes. I personally think he wanted to get rid of me thats why he said these things. This is the second time he wanted me to leave him. He then called me after one week and said I should come back to him. I asked if he is changing his religion. He said No. Then I asked "You said there is no God". He replied, I wasn't accurate. I believe there is some one kalma is correct but I don't believe in religious practices and don't like people giving names to God. I told him we cant live together if you wont be a Muslim. He said I didn't change anything. He said he is scared to change the religion and he is scared to say anything because he might not be considered as Muslim. I asked so you believe in Allah. He said yes. He pray sometimes and he fast the whole month of Ramadhaan but he thinks that people might have altered Qur'an just like bible. He lacks knowledge of Islam. Now my question is, is my nikaah still valid? Is he still considered to be a Muslim? I didn't go back because I am very confused.
