Work hard on removing hatred for fellow brothers and sisters in Islam and learn to hate sins instead. We will hate the shirkh or biddah but we will love the brother or sister, this is a person who has declared the shahadah the same as me. 

When you see a brother with a bottle of alcohol in his hand, a bad Muslim will take that picture and post it all over social media, a good Muslim will go and advise in a kind way to quit this habit and Allah may open his heart through your effort.

When Allah uses you to guide someone in this world this is better than anything in this world. Make dua for your brothers and sisters to purify our hearts. If Allah wills that person will come to the path of Allah.
