Hadith

Hadiths are sayings of the Prophet (S.A.W.). There are many hadiths, but I am going to list 2 that are effective to me and why.

1. The best of your leaders are those whom you love and who love you, who pray for you and you pray for them. The worst of your leaders are those whom you hate and who hate you, and you send curses on them and they send curses on you.

This is effective to me because it tells me that you should always be a good leader rather than a negative hater and have care for your companions

2. You will (must) enjoin the good, and you will (must) forbid the evil, or Allah will make sovereign over you the worst of you, who will afflict you with the worst of punishment, then the best of you will make Du’a and it will not be answered. 

This is effective to me because it tells me that you must be good rather than a horrible person, so you do not get severely punished in Jahannam.
