Not letting our mood affect the way we treat people is a forgotten sunnah

You can't just pretend that the things you watch, and the things you hear, and the places you go will not have an impact on your character. They will.

Every single success you experience is a combination of two things: your effort and Allah's help. When you don't put in enough effort, Allah does not give His barakah. And sometimes you might put in a lot of effort but you may not see the result you expected. That, also, is Allah's barakah.

Change your 'Nafs', change the world.

If you have friends or family who are not practicing, give them your company and not your judgment. They need your patience and your love. Allah is sufficient for judgment and He subhanahu wa ta'ala is a perfect Judge. We are not.

When you see someone who is not as religious, remember that you were once on the edge of the fire, and it was Allah Subhaanahu wa Ta'ala's favor upon you to guide you. Arrogance will wipe away any goodness from the transformation.

The more knowledge (of deen) you have the more humble you should be. Instead you are becoming judgemental.
