God is Al-Shaakir (The Grateful) and Al-Shakoor (The Appreciative). He is the One Who appreciates even the smallest deed, and He forgives the greatest mistakes. He increases good deeds and appreciates those who give Him thanks. God remembers those who remember Him.
“And they will say: ‘All the praises and thanks be to Allah, Who has removed from us (all) grief. Verily, our Lord is indeed Oft Forgiving, Most Ready to appreciate (good deeds and to recompense).’” (Quran 35:34)
From the sayings of Prophet Muhammad, we learn:
“God has written down the good deeds and the bad ones. He who has intended a good deed and has not done it, God writes it down as a full good deed, but if he has intended it and has done it, God writes it down as from ten good deeds to seven hundred times, or many times over. But if he has intended a bad deed and has not done it, God writes it down as a full good deed, but if he has intended it and has done it, God writes it down as one bad deed.” (Saheeh Al-Bukhari, Saheeh Muslim)
