There is a difference between the validity of actions and the acceptance of actions; what is mentioned in jurisprudence in terms of the conditions of the person praying, such as clean clothes, a clean body, a clean place, correct recitation, etc., and which refers to the appearance of the prayer, will cause the prayer to be valid; not its acceptance; because the conditions for acceptance are related to the inner nature of worship and its spiritual and mystical effects.

The validity of a prayer means that there is no qadha, return, or punishment, and the person has fulfilled his duty; but the acceptance of a prayer has other conditions, including the presence of the heart, eating halal food, and the absence of a forbidden morsel in the body, etc.

One of the conditions for acceptance that God states in the Quran is piety; In verse 27 of Surah Al-Mandah it is stated: And recite to them the story of the two sons of Adam in truth: When each of them did something to draw near (to Allah), but it was accepted from one and not accepted from the other (the brother whose deed was rejected said to the other brother): “By Allah, I will kill you!” (The other brother) said: “(What is my sin? Because) Allah accepts only from the righteous!” Just as transgression prevents the acceptance of worship; in verse 53 of Surah At-Tawbah we read: Say: “Spend (in whatever way you wish) willingly or unwillingly, it will never be accepted from you, for you are a rebellious people.”
