Unlike others, I am not offering salah in a particular mosque regularly because I know it is built on government land, which is not purchased. Government is not allotting/selling this land for mosque & want to demolish it. I hope, I am not doing sin. Please revert.
بسم الله الرحمن الرحيم
(Fatwa: 367/360/B=3/1439)
You should offer salah in your nearby mosque i.e. in the mosque of your Mohalla. It is not good to leave Mohalla mosque and miss jamat without a reason. If according to your opinion it is not a Shariah mosque yet you will be getting the reward of offering salah and jamat. Thus you should offer salah in the mosque of your locality regularly.
Allah knows Best!
