[Surah Al-Qalam 68:4]
The Arabs were unlettered except for a few. The blessings of Touhid made them efficient and useful members of the society. Knowledge of Touhid is called Ilmun Nafe, the beneficial knowledge. Quran calls all those who reject the knowledge of Touhid as blind, deaf and their hearts sealed (due to their ignorance).
Allah has sealed their hearts so their hearts will not respond to do good deeds, their ears would not pay heed to any preachings of goodness and their eyes would not be able to differentiate between the right and wrong. The words of Touhid open up the eyes, ears and hearts. That is why it is essential to work hard in learning Deen and this is one of the missions of the prophethood “Indeed I am sent to teach Deen.”
He commanded his Companions:
“Teach people. Give them glad tidings of the virtues of learning Deen, do not speak anything that can cause people to flee, make things easy for them and do not make things difficult for them.”
Teaching and glad tidings go hand in hand.. Today many religious scholars and teachers have discarded this precious advice.
The Qur’an and Hadith are full of virtues of learning Deen
One of the glad tidings is mentioned in Sahih Muslim.
One day our Prophet ﷺ said:
“If I say that the valley of Aqeeque has a person, who gives a camel to whoever visits him, then who would like to go and meet him?”
Everyone was ready to go and take along all their sons,too, to collect as many camels as they could.
The Prophet ﷺ explained:
“By Allah! If you sit in this gathering and learn one verse, it is more precious than getting a camel as a gift. If you learn two verses, it is more precious than getting two camels as a gift.”
