Al-Imâm Ash-Shaafi was reported to have composed:

All knowledge save the Qur’aan is a mere preoccupation Except hadith and the knowledge of jurisprudence in Deen.

The profession you learnt in the university is nothing but a meal ticket like the skill of any artisan. Everyone of you contributes their quota to the Gross Domestic Product. So why bamboozle us with your academic feat? After all when you die, and you are going to die, you will not be buried with your certificates. So what is the problem?

Lest you think we are Yusufiyoon(i.e backward), there is some good in the contemporary knowledge, it is part of the bounties of Allah over the slaves. Here are we punching this gadget to pass on this message, Ni’mah Wallaahi! And the HTML we used to make it readable for all. We have doctors who help the Muslims in their clinics. An architect and an engineer had done a wonderful job the last time at our Madrasah here. But these people don’t pride their professions over Islam. When you see them you take them for Mallams in Madrasah, and they are. This is what we desire not professions at the detriment of Islam, such that you open a stinking mouth and say those who get busied with the learning of the Deen are retrogressive and waste. May the hand that type, and the mouth that utters that, be despised.

So,

ﻟَﻴْﺴُﻮﺍ ﺳَﻮَﺍﺀً

‘... they are not the same...’ [Aal Imraan, 113].

There are among the Ikhwah who are medical doctors, engineers, scientists, etc. that know their limit. They seek the knowledge of the Deen, use their professions to help the cause in anyway, respect the teachers and learners of Islam…

ﻭَﻣَﻦْ ﺃَﺭَﺍﺩَ ﺍﻵﺧِﺮَﺓَ ﻭَﺳَﻌَﻰ ﻟَﻬَﺎ ﺳَﻌْﻴَﻬَﺎ ﻭَﻫُﻮَ ﻣُﺆْﻣِﻦٌ ﻓَﺄُﻭﻟَﺌِﻚَ
ﻛَﺎﻥَ ﺳَﻌْﻴُﻬُﻢْ ﻣَﺸْﻜُﻮﺭًﺍ

‘And whoever desires the Hereafter and strives for it, with the necessary effort due for it while he is a believer (in the Oneness of Allâh), then such are the ones whose striving shall be appreciated, thanked and rewarded (by Allâh). [Al-Israa, 19].

But you, who thinks your scanty knowledge about the world is your key to Jannah such that you lampoon the people of knowledge and its learners, be sure that your lot is ignominy unless you repent and chart a new course. That we let you know this, can never be a kaffaarah(expiation) for you as you have thought.

ﻭَﺍﻟﺴَّﻼﻡُ ﻋَﻠَﻰ ﻣَﻦِ ﺍﺗَّﺒَﻊَ ﺍﻟْﻬُﺪَﻯ

Peace unto whoever follows the guidance.
