At the Madrasah, time is not allowed for performing the two raka'ts Nafl of Maghrib.

Answer

The molvi sahibs and the students have much time for even sport and nonsensical conversation, etc., but are deceived by shaitaan regarding Nafl and Mustahab acts. It is essential that Awwaabeen, Ishraaq, Chaasht, Tahyatul Wudhu, Tahajjud, etc. be inculcated in the students. After all, the Maqsad of Ilm is to make Amal. But Amal is disdained in the madaaris of this era. They teach Deeni knowledge for the sake of the dunya, not for the Aakhirah, hence their focus is on making zulm on Nafl Ibaadat which is so essential for cultivating spiritual fibre and proximity to Allah Ta'ala. Nowadays, Ilm is imparted for the dunya, not for the Aakhirah, hence the molvis are generally bereft of Taqwa and A'maal-e-Saalihah. This evil attitude and habit are cultivated in the Madaaris. Islaah is Waajib from infancy.
