When is worship pure for the sake of Allah?

Question:
May Allah reward you. From the questions of the questioner Ibrahim, the Honorable Shaykh says: How is worship to be pure for the sake of Allah, Mighty and Majestic?

Answer:
It is pure for the sake of Allah, Mighty and Majestic, if it is free from shirk (associating partners with Allah). If the intention of its doer is free from major shirk, such as supplicating to other than Allah, slaughtering for other than Allah, or making vows for other than Allah, and from minor shirk, such as showing off in worship and seeking fame, then if it is free from major and minor shirk, it becomes pure for the sake of Allah. This is because the servant's intended goal is the Face of Allah, Mighty and Majestic, with no other intention, or if he takes to supplicate to, hope from, slaughter for, or make vows for. Yes.
