All praise be to Allah Alone. May Allah's peace and blessings be upon the Last Prophet.
Undoubtedly, knowledge is the basic foundation of human life, and the knowledge which is most worthy of care and attention is that of Islamic Shari`ah. Knowledge of the Islamic Shari`ah helps the individual to grasp the wisdom for which Allah (may He be Praised) created us and sent His messengers. It is the knowledge through which man knows Allah (Exalted be He) and how to worship Him.
And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone).
And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): "Worship Allâh (Alone), and avoid (or keep away from) Tâghût (all false deities i.e. do not worship Tâghût besides Allâh)."
Or do you think that most of them hear or understand? They are only like cattle nay, they are even farther astray from the Path (i.e. even worse than cattle).
O you who believe! Answer Allâh (by obeying Him) and (His) Messenger when he (ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) calls you to that which will give you life
Whoever works righteousness whether male or female while he (or she) is a true believer (of Islâmic Monotheism) verily, to him We will give a good life (in this world with respect, contentment and lawful provision), and We shall pay them certainly a reward in proportion to the best of what they used to do (i.e. Paradise in the Hereafter).
Beneficial knowledge is only acquired through a teacher, who must be well aware of the subject he is teaching, since the one who lacks something cannot give it. Scholars are the inheritors of the prophets. Therefore, teaching has proved to be the most difficult task due to the perfect qualities a teacher should have in terms of beneficial knowledge, good morals, continuous righteous deeds, patience and the ability to bear difficulties for the sake of correcting the student and giving him a pure Islamic upbringing.
The best among you (Muslims) are those who learn the Qur'an and teach it.
If Allah guides aright even one man through you that is better for you than to possess the most valuable camels
Whoever guides to something good will have a reward similar to that of its doer.
So when they turned away (from the Path of Allâh), Allâh turned their hearts away (from the Right Path).
And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time, and We shall leave them in their trespass to wander blindly.
