Assalāmu 'alaykum wa rahmatullaahi wa barakaatuh...
I wanted to post this as a reminder for myself first and then everyone else who is attending the weekly Kitaab at-Tawḥīd Classes with Brother Mūsá...since we are learning more and more every week, and acting upon what we know is mandatory...I hope this article will be of some benefit for everyone...(it's a bit lengthy but well worth the read)...
From the Introduction of the book: Knowledge Mandates Action
(By: Imām Abū Bakr Aḥmad bin ‘Alee al-Khateeb al-Baghdaadee - with verification and notes by Imām Muhammad Naasir-ud-Deen al-Albānī)
We give thanks to Allaah, the One free of all defects, for having guided us. And we ask Him to grant us the ability to act upon what He has given us knowledge of, for indeed, goodness cannot be attained except by His success and assistance. Whomsoever Allaah leads astray, there is no one from His creation that can guide him.
May Allaah send His praises upon Muhammad (ṣallallāhu ‘alayhi wa sallam), the chief of the first and the last, as well as his brothers from among the prophets and messengers, and those who follow the light (i.e. the Qur’aan) that was revealed to him (ṣallallāhu ‘alayhi wa sallam) until the Day of Recompense.
I advise you O seeker of knowledge to have a sincere and pure intention in your search for knowledge, and that you exert yourself in acting upon what it mandates (from action). This is since knowledge is a tree and action is its fruit. And one can never be considered knowledgeable so long as he doesn’t act upon what he knows.
It has also been stated: “Knowledge is a parent and action is its offspring” and “Knowledge comes with actions, while narrating comes with investigating.”
So do not feel satisfied with actions so long as you are lacking in knowledge, nor feel satisfied with knowledge so long as you fall short in producing actions. Rather, combine between them both, even if your share of the two is small.
And there is nothing worse than a scholar whose knowledge the people abandon because of the corruption of his ways, or an ignorant person whose ignorance the people accept because of what they see from his worship.
So a little of this (knowledge) along with a little of that (action) is what is most likely to save you in the end, when Allaah bestows His mercy upon His servants and completes His favor upon him. But as for laziness and negligence, love for ease and comfort, preferring the easy life, showing indifference, and inclining towards leisure and relaxation, then the results of these characteristics are blameworthy, detestable and disastrous.
Knowledge leads to action, just as actions leads to salvation. So if the action falls short of the knowledge, then the knowledge becomes a burden upon the one who possesses it. And we seek refuge in Allaah from knowledge that turns into a burden, brings about humiliation, and becomes a shackle on the neck of the one who possesses it.
Some of the wise people have said: “Knowledge is the servant of action” and “Action is the main objective of knowledge – so if it were not for action, knowledge would not be sought, and if it were not for knowledge, actions would not be sought. And if I were to not follow the truth out of ignorance of it, that would be more beloved to me than if I were to not follow it out of intentionally abstaining from it.”
Sahl bin Muzaahim, (may Allaah have mercy on him) said: “The matter is tighter upon a scholar than when one clenches his fist. Even though an ignorant person is not excused because of his ignorance, a scholar will still receive a greater punishment if he abandons what he has knowledge of and doesn’t act upon it.”
So did those of our Salaf (predecessors) from the past reach the high levels that they did except through sincerity in Creed (Beliefs), righteous actions and overwhelming abstinence of the attractive features of this worldly life? And did the wise people reach the greatest level of success (that they did) except by working hard in their efforts, being pleased with little sustenance, and giving away any of their excess provisions to the poor and needy?
Is not the one who collects books of knowledge just like the one who collects gold and silver? Is not the one who has an intense craving for them just like the one who yearns and longs for gold and silver? Is not the one who is deeply in love with them just like one who treasures gold and silver?
So just as there is no benefit in wealth unless it is spent, then likewise, there is no benefit in knowledge unless it is acted upon and its obligations carried out.
Therefore, let each individual examine himself and take advantage of his time, for indeed the resting place (i.e. this world) is short, the (time for) departure is near, the road is hazardous, deviating from it is common, the danger is great, the one who takes himself to account has insight, Allaah, the Most High, is watching, and to his is the (final) recourse and return.
“And whosoever does an atom’s weight of good, shall see it. And whosoever does an atom’s weight of evil, shall see it.” [Surah az-Zilzaal: 7-8]
It is reported that Abu al-Dardaa(may allaah be pleased with him) said: "You will never be pious (a person of taqwa)until you become knowledgeable, and you will never be beautiful with your knowledge until you act (by it)." [Ibn 'Abd al-Barr, Jami' Bayaan al-'Ilm wa Fadihi']
