You will be dealt with as you deal with others...
You will be dealt with as you deal with others, you will reap what you sow, and what you send today will meet you tomorrow. So provide for your future and send (some good acts) for your day (of reckoning). Fear, fear, O listener! Act, act, O careless one! “None can inform you like the One who is aware” (35:14).
One of the firm decisions of Allah in the Wise Reminder (Qur'an) upon which He bestows reward or gives punishment, and through which He likes or dislikes is that it will not benefit a man, even though he exerts himself and acts sincerely if he leaves this world to meet Allah with one of these acts without repenting, namely that he believed in a partner with Allah during his obligatory worship, or appeased his own anger by killing an individual, or spoke about acts committed by others, or sought fulfilment of his needs from people by introducing an innovation in his religion, or met people with a double face, or moved among them with a double tongue.
اعْقِلْ ذلِكَ فَإِنَّ الْمِثْلَ دَلِيلٌ عَلَى شِبْهِهِ. Beasts are concerned with their bellies. Carnivores are concerned with assaulting others.
