The Family Of Imran - 3:15 "Say: "Shall I inform you of something better than that? For the righteous there are gardens with their Lord beneath which rivers flow, gardens in which they will abide forever, immaculate wives, and happiness because they have won the approval of Allah."Allah sees the servants."
Allah does not diminish the reward of the believers for their good deeds, but gives it in full:
The Family Of Imran/3:195 "Their Lord answered them: "I will not leave unrewarded any of you who works, whether male or female; you are all equal. Those who emigrated, those who were expelled from their homes, those who were tortured and insulted in My way, those who fought and were killed... I will cover their evil deeds and place them in gardens with rivers flowing in them as a reward from Allah. The best reward is with Allah."

The One Covering Himself/73:20 Your Lord knows that you and a group of your companions get up less than two-thirds, half and one-third of the night. Allah determines the amount of the night and the day. He has forgiven you because He knows that you cannot do it. So read from the Qur´an as much as is easy for you. He knows that among you are the sick, those who seek sustenance from the bounty of Allah in the earth, and those who fight in the way of Allah. Read from it as much as is easy for you. Observe the prayer, pay the zakat, and make a debt to Allah through good deeds. Whatever good you do for yourselves you will find a better and greater reward in the sight of Allah. Seek forgiveness from Allah; Allah is Forgiving, Merciful.
