No ones perfect!!

Asalamu Alakyam Waramatullahi Wabaraktuh.
Just because someone is religious doesn't mean their perfect (I take refugee in Allah). People need to understand no one is free from mistakes or blemishes other than Allah Subhana Wa Tala. As a Muslim we strive and struggle everyday to correct our intentions and strive in Allahs path. All I can say is if someone is trying than you should appreciate that and recognize that in itself is half the solution. No one fully changes in a matter of weeks or even months for that matter and you can't expect someone too. It takes time, its a gradual process. People do not have a right to judge and criticize you in a negative manor. There's a big difference between nasheeha (advice) and putting someone down. When you say things that are meant to be vicious or condensing your hurting yourself and even worse the person you said that too.
We aren't perfect and Allah says that verily man are created weak. I feel as If people have this image in their mind of how a person should be or act. And when a person doesn't fulfill their expectations they become outraged or looked down upon. SubhanAllah, that's when problems occur. However if a person gets mad and says things they shouldn't have. We shouldn't reply back in hurtful words but accommodate them. Accept that they are human and they are trying to be better and that's ultimately whats important. I believe we never stop growing spirituality, we are always in constant need of knowledge and guidance.

My advice is do not get discouraged, stay strong on your goals. Make dua for anyone who has harmed or oppressed you. Forgive your Muslims brothers and sisters, indeed that is the best way. Have mercy on other and Allah will have mercy on you.
