Do the angels say "Amen" to the supplications or thoughts that the soul speaks of, even if they are not uttered?

A Muslim is not held accountable for what he thinks to himself or what his devil whispers to him, as long as he does not act upon it or speak of it. This is based on the saying of the Prophet, peace be upon him: "Indeed, Allah has forgiven my Ummah for what they think to themselves, as long as they do not speak of it or act upon it." This includes all thoughts that come to mind, whether the thought is backbiting, disbelief, or anything else. So, if disbelief merely crosses one's mind as a fleeting thought, without any intention to pursue it, and then one immediately dismisses it, then one is not a disbeliever, and there is no blame upon him. The reason for this forgiveness is the difficulty of avoiding such thoughts; what is possible is to avoid dwelling on them. Therefore, if they are merely thoughts of satanic whispers, there is no blame upon you for that, and you must repel these thoughts from yourself. Angels say 'Ameen' to those who pray for good, but they do not say 'Ameen' to the whispers, thoughts, and self-talk that Satan introduces into your heart.
