God's reward

i love listening to the late Dato' Ismail Kamus's preaches. i learn a lot from his preaching. One of them was if we die, please don't depend on other people to pray for us, for example tahlil kenduri from our family, Quran recitation from them. He asked us to work hard when we are still alive to get reward from God. We, ourselves work hard for our paradise or heaven investment. there are so many good things we can do like performing prayers, fasting, donating, helping people, switching off fans and lights when there's nobody in the room, picking up plastic or rubbish on the floor because we don't want people to fall when they step on it. His advice was simple but can we do it? ok good bye and take care.
