Aslaamu alaikum
If a Muslim does not know about a certain sunnah. For example it’s a Sunnah to sit and eat or drink.
The Muslim is told or hears it from someone else that they should eat and drink by sitting. And the Muslim due to lack of knowledge says, that’s not right/true or that can’t be right’.
Does this affect the Muslims Imaan. Does the Muslim get kicked out of Islam?
The Muslim does not disagree with any Sunnah or law of Islam but due to lack of knowledge he/she says that ‘that’s not right or that can’t be right’.
