Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
Is the Messenger of Allah ﷺ aware of our thoughts, just as he is aware of our sending greetings of salam to him?
He has access to our thoughts, but the question is whether he pays attention to them, since he is completely focused upon his Lord. He pays attention to thoughts that pertain to him or his call to Allah, and thoughts that are of benefit to his Ummah.
