that is because allah never changes a blessing that he has bestowed on a people unless they change what is in their own souls and allah is allhearing allknowing like the precedent of pharaohs clan and those who were before them who denied the signs of their lord so we destroyed them for their sins and we drowned pharaohs clan and they were all wrongdoers.
ذلك بأن الله لم يك مغيرا نعمة أنعمها على قوم حتى يغيروا ما بأنفسهم وأن الله سميع عليم كدأب آل فرعون والذين من قبلهم كذبوا بآيات ربهم فأهلكناهم بذنوبهم وأغرقنا آل فرعون وكل كانوا ظالمين
