And today there is no room for half measures in knowledge.
Seek useful knowledge as Allah enables, be sure of it, and shun half-learning.
Today, some harm Sharia, misread Islam, and add to religion what isn't from it.
They settle for half-measures. They know some things; others escape them.
And this does not absolve one.
One is not absolved if able to research, yet merely settles for what one learned.
One studies in college, then forgets half, and doesn't review. Can he lead people?
There must be depth, for you convey on behalf of Allah ﷻ.
Knowledge is not easy, and the Ummah needs very many scholars.
How large is the Ummah?
1.5 billion.
How many scholars do we need? How many specialists do we need?
He learns something, preaches it, and explains Allah ﷻ's law.
Allah ﷻ commanded us to follow and to convey it.
Conveying is not done in ignorance. It is done with knowledge.
You need firm knowledge, according to your ability, so be diligent.
And Allah ﷻ knows you did your best.
