once there was this man. he was poor and really wanted and animal to travel with. a man saw his needs and gave him a horse. he told him that the horse was very obedient and a very fast runner! he told him the following things:

to make it walk, say: "Subhaanallah"

to make it run, say: "Alhamdulillah"

to make is stop, saw: "Allahuakbar"

So he tests it by making it run by saying Alhamulillah and making it walk and stop.
The poor man was very happy indeed that he had this horse and thanked the owner a lot. The owner told the poor man to play with the horse and get to know it.
so the man starts to take it around the whole city and town. he takes him to the market by making it walk, run, and stop. he starts going further to the places like grass land and cliffs.
But Once he was driving it, he was heading right towards a very dangerous cliff!! he was in TOTAL PANIC and had no idea what to say. he for got everything, he tried mashaallah, and astaghfirullah and was really in panic.

Atlast he rememberred and said "ALLAHUAKBAR!!!" The horse finally stopped and the man raised his hands in the air and said "Alhamdulillaah".
