﴿ كَبُرَ مَقْتًا عِندَ ٱللَّهِ أَن تَقُولُوا۟ مَا لَا تَفْعَلُونَ ﴾

“Most loathsome is it in the sight of God that you say what you do not do!”

(It is most hateful in the sight of Allah that ye say that which ye do not) that you promise that which you cannot fulfil or speak of doing that which you cannot do.
