When you find yourself in a position to help someone, be happy because Allah is answering that person's prayer through you.
وَلَا تَيْئَسُوا مِنْ رَوْحِ اللَّهِ إِنَّهُ لَا يَيْئَسُ مِنْ رَوْحِ اللَّهِ إِلَّا الْقَوْمُ الْكَافِرُونَ And do not lose hope in the mercy of Allah; indeed none lose hope in the mercy of Allah except the most ungrateful people.
I'm sorry.. I'm too arrogant and selfish. Ya Allah forgive me too, make me the one who keep humble and always understand others in any situation of my life..
