We do believe Muhammad(saws) was carried to a heaven by a creature of some type. It was something Muhammad(saws) had never seen before and never saw again. We do not know what it was except it was sent by God(swt). No where did Muhammad(saws) call it a winged horse.
Dog Memory Span. To be able to make a somewhat complete analysis about the span of dog memory, it is important to differentiate between associative memory and real memory. It is said that if a dog does not have some sort of exterior stimulus that he is not able to think about or remember parks or places he has been in before. But as soon as dog hears his owner's voice, smells him or perceives his presence at a distance, his associative memory activates or comes to life.
Sorry to break it to you, but your dog probably has no recollection of that fun game of fetch the two of you played yesterday. And that yummy treat you gave him just minutes ago? Even that has probably gone poof! The truth is, a dog's memory just isn't very good. And a new study suggests that the same is true for 25 other animal species, from bees and birds to big mammals. Their recall of specific events disappears within minutes or even seconds.
