Why is the mention of faith in Allah and the Last Day repeated in the texts more than the other pillars of faith?

Question:
The Honorable Shaykh, may Allah grant you success, says: Sometimes the mention of prayer and zakah appears without the other pillars of Islam, and also in the hadith without the other pillars of faith. What is the intended meaning of this? And what is the wisdom behind it?

Answer:
Because the one who believes in Allah and the Last Day will fulfill the pillars of faith and the attributes of faith; he is not a believer except by that. If he believes in Allah and the Last Day, he will fulfill the attributes of faith. The Messenger did not mention them here because he explained them in other hadiths, and the hadiths are combined with one another; what is on one side is explained by the other, clarifying, specifying, and detailing one another. As for the times when prayer and zakah are mentioned, we referred to this during the lesson. We said that prayer is the head of physical deeds. Whoever preserves it, the rest of the acts of worship become easy for him. Whoever preserves it, the rest of the deeds become easy for him.
Zakah is the head of financial deeds. So whoever pays zakah, the rest of spending in the path of Allah the Exalted and Majestic becomes easy for him. And whoever is stingy with zakah, the rest of the deeds will not be easy for him. And whoever is negligent in prayer, he is negligent in other things.
Therefore, it came in the athar: "Whoever preserves it, meaning prayer, and maintains it, he preserves his religion. And whoever neglects it, he is more neglectful of what is other than it." Allah the Glorious and Exalted said: There are two great matters in prayer. The first is that it forbids immorality and wrongdoing, so it accustoms the person to obedience and makes him hate [immorality]. The second is that it contains the remembrance of Allah, Glorified and Exalted is He. The remembrance of Allah is greater than all other deeds. Yes, all of this is gathered in prayer. Yes.
