I’ve heard words like malakut, jabarut, lahut … etc but don’t know what they mean. Could you please explain what they mean and the difference between them?

Also I’ve heard different interpretations for the seven heavens and seven earths. What is the most common interpretation among our scholars?

These are different types of worlds discussed by our Islamic philosophers and to some extent mystics
1. Malakut- the world of souls or lights

2. Jabarut- the world of intellect

3. Lahut- the world of Allah’s beautiful names and attributes

4. Nasut: Material world

Note that all these worlds precede the material world
