I see the moral and spiritual conditions of the Darul Ulooms swiftly degenerating.

Answer

Alhamdulillah, your thinking is correct. Allah Ta'ala has bestowed good understanding to you. It is necessary to understand that the predictions of Rasulullah (Sallallahu alayhi wasallam) must materialize. He said that the time will come "when the worst of the people under the canopy of the sky will be their ulama." Rasulullah (Sallallahu alayhi wasallam) further said: "They will be shayaateen in human bodies.", and that they will be imams who will mislead the Ummah.

We are seeing the predictions of Nabi-e-Kareem (Sallallahu alayhi wasallam) materializing in front of our eyes. Things will not improve. On the contrary, the situation will become worse. We are living today in a virtual spiritual minefield. Pick your way carefully to avoid getting blown up by the corruption which shaitaan and his agents are planting.

Almost all the Darul Ulooms are promoting haraam activities. Almost all the students studying at these darul ulooms emerge with convoluted minds. They use the Deen to gain the dunya. May Allah Ta'ala have mercy on us.
