Abu Hurairah reported,

The Prophet ﷺ said that Allah said, "When My servant intends to do a good deed, I record it as one good deed for him as long as he has not done it. When he carries it out, I record it as ten times its like. And when he intends to do a bad deed, I forgive it for him as long as he has not done it. When he carries it out, I record it as one of its like."

عن أبي هريرة

عن النبي ﷺ قال: قال الله عز وجل: إذا تحدث عبدي بأن يعمل حسنة فأنا أكتبها له حسنة ما لم يعمل، فإذا عملها فأنا أكتبها بعشر أمثالها، وإذا تحدث بأن يعمل سيئة فأنا أغفرها له ما لم يعملها، فإذا عملها فأنا أكتبها له بمثلها.
