Now, Allah will test us through people too. There will be some people who become too extreme, and some who become too liberal; what this leave us is the majority of people who just want to do the best they can for Allah. This interpretation is something that Nouman Ali Khan suggests, and I can see how this makes sense.

You focus on yourself, and if you are trying your best to educate your friends or family about the deen, try not to get too bogged down if it's not being received effectively; your job was to convey the message, the rest - that is, the guidance, comes from Allah.
