"Why must i be the cause for someone to be thrown into the hell fire?"
[Imam Ahmad Ibn Hambal]
Yes, it's hard to do that. Whenever we are hurt by someone's statement or action, we are furious, and we know that Allah is the fairest of all, The Just. With this, we know that Allah will pay us back with whatever that we did in this world, good or bad. So, if we are on the right side, the people who hurt us will get somewhat a punishment for what was done to us.
But what did Imam Ahmad Ibn Hambal reply to this kind of actions and behaviour, he forgive those who did wrong to him. Why? because of this statement, "Why must i be the cause for someone to be thrown into the hell fire?". Subhanallah. Even with the challenges and pain that he had to go through, he can still forgive and ask forgiveness from Allah for these people.
It's hard. There is no doubt about it. But it is not impossible as well. Allah will always rewards us for our patience and effort to seek for His love and guidance.
Seek help in patience and prayer; and truly it is hard save for the humble-minded, (45) Who know that they will have to meet their Lord, and that unto Him they are returning.
So lets take this as a motivation to be a better person in our life starting from now!
P/s: He knows what one's heart need and He give just the right tarbiyyah at the right time, SubhanAllah!
