Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaih) once mentioned:
My beloved brothers! I wish to mention something of great importance to you which I have not mentioned before. You are ‘Ulamaa and Ustaads and many of you are perhaps responsible for the administration of various Deeni institutes. All these institutes of Deen are in actual fact continuing to function through your efforts and barakah. May Allah Ta‘ala accept all these Deeni institutes and may He accept the learning and imparting of Deen that is currently taking place in them.
My beloved brothers! My advice to you is that when you run your Deeni institute then do not adopt an approach or do anything through which you will cause other Deeni institutes to be regarded as insignificant and unimportant. Through the grace and Fazal of Allah Ta’ala, there are currently many Deeni institutes operating in India and Pakistan. The Ulama of these Deeni institutes should all consider my advice and take it to heart. Running down other Deeni institutes (or other Deeni efforts) is a very destructive disease and this disease, in actual fact, stems from pride. Hence, one should strive to create humility within oneself. In this regard, we should follow the example of our pious predecessors. (Malfoozaate Hazrat Shaikh 2/158)
