Do I have to redo my ghusl if I used a cup to pour water?
Thank you for your question. The situation that you describe is perfectly sufficient for a valid ghusl. Pouring from a cup ensures that you do not waste water, and that is one of the sunnas of the ghusl which is difficult to follow these days. You should use also rub the water all over, as this is sunnah and serves to spread the water to every area.
The two integrals of the ritual bath in the Shafi’i school are a) the intention) and b) that water reaches all of the skin, hair, and nails. Please consider taking a course on personally obligatory fiqh of worship.
Take every measure to ignore baseless misgivings (waswasa). Allah wants your worship to be easy and not cumbersome. Once you take a course on the subject, the Devil will not have his way with you, and you will have the confidence that you need to proceed with ease. May Allah reward you for your sincerity and give you the best in this world and the next.
