This is commonly asked and also commonly misunderstood! Should we worship Allah out of love or fear?
We should worship Allah out of love because Allah created us, Allah is merciful to us, Allah instructed us and He is the Creator. So where does the factor of fear come in?
When you worship Allah and you live by the commandments of Allah, you see that there is an emphasis on both hope and fear. Some people are moved by fear more than hope and some people are moved by hope more than fear. It varies depending on the person. However, we need to have a balance of the two.
