When a nation is negligent towards Salah, and none prohibits them against this/cautions them except that the first punishment to afflict them will be a decrease of sustenance.
The performance of Salah is closely linked to one’s sustenance. In Surah Taha, Allah Ta’ala mentions “Instruct your family to perform Salah and be steadfast in [performing] it. We do not ask you for provision. We provide for you”
(Surah Taha, Verse: 132)
Hafiz Ibn Kathir (rahimahullah) states under the commentary of this Verse: “If you establish Salah, sustenance will come to you from avenues you did not anticipate”
(Tafsir Ibn Kathir, Surah: Taha, Verse: 132)
And Allah Ta’ala Knows best.
