Hi,
Devil, Satan and iblis, are the same names. Mostly used for Devil.
The devil speaks to us but we can not hear and can not see. We just realize that Satan or devil is a spiritual being.
He may be able to "whisper" spiritually to us. He may be able to provoke, in some manner a thought or an idea. But, he does not have control over our minds or our bodies.
Every time we have two ideas about anything like bad or good. In most cases, we follow bad ideas or thinking. He tempts us and tries to deceive us.
He whispers to us that our sins aren’t so bad. And most often we think both things like good and bad but we follow bad things. He only invites us.
Here are some of the Quranic verses that make the boundaries of the portrait more defined:
Allah says in Quran chapter# 4, verse #114
"From the evils of sneaky whisperers.[Quran 114:4]
Allah says in Quran chapter# 16 and verse# 99-100
"He has no power over those who believe and trust in their Lord. His power is limited to those who choose him as their master, those who choose him as their god".
