ما المقصود بتناقص العبادات؟

"Decreasing acts of worship" is not a known concept. However, if what is meant by it is that the bonds and obligations of Islam will be undone one after another, then this is true, and the hadith supports it: "The bonds of Islam will be undone one by one. Each time a bond is undone, people will cling to the next. The first to be undone will be governance, and the last will be prayer."
