Shaykh Syed Abul Hasan Ali Nadwi (Allah have mercy on him) said the following addressing the students of Medina (al-munawwarah) University,
‘A scholar should be more pious and congnizant (of Allah).
Being excessively involved in contraversial issues makes one negligent of his/her own personal improvement.
Focus more on practice of issues that are held unanimous. For example, khushu in salah. Do not be involved in peripheral minor issues.
You are aware of the scholarly acheivements of Imam Ahmad and Hafiz Ibn Taymiyyah (Allah have mercy on them). However, you are not aware of their high moral character, humility, fear of Allah and being busy in night crying.
It was the practice of Hafiz Ibn Taymiyyah (Allah have mercy on him) that whenever, he faced a difficulty he would go to an isolated mosque, cry and make the following supplication repeatedly,
Ya mu’alim al Ibrahim ‘alimni, ya mufham al Suleman fahimni
The greed and desire of the worldly has made the scholars worthless.
Be an example for others.’
