Allah (SWT) is pleased with noble deeds done by His sincere servants, and is unhappy with sinful acts and wrong doers.
We should never think that Allah (SWT) has feelings like our feelings. Our feelings are based on benefit or loss and our thinking while Allah (SWT) is above any benefit or loss. The pleasure of Allah means His blessings on the sincere good doers. His anger is the result of bad deeds. Allah is The Absolute Needless and there is no question of any benefit nor loss or materialistic feelings.
