Allah - glory be to Him and may He be exalted! - has given inanimate objects awareness and perception by which they glorify their Lord. The stones fall down out of fear of Him. The mountains and trees prostrate. The pebbles, water, and plants glorify Him. All this is going on but we are not aware of it. Allah the Great said, "There is nothing which does not glorify His praise, but you do not understand their glorification". (Quran 17:44) The companions heard the food that was being eaten glorifying Allah. That was because the companions had a transparency of heart that does not now exist among us. All these things are part of our world and yet we are in complete ignorance of them.
