All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
It is Islamically required to endeavor to earn one’s living; Allaah Says (what means): {It is He who made the earth tame for you, so walk among its slopes and eat of His provision and to Him is the resurrection.}[Quran 67:15] Therefore, a Muslim should endeavor to earn his living and the living of the people whom he is obliged to spend on. The Prophet said: “It is enough a sin for a person not to provide means of sustenance to those whom he is obliged to support.” [Ahmad and Abu Daawood]
Therefore, if you do not have what is sufficient for you and for the people whom you are obliged to spend on, like your wife, your parents and your children, then it is not permissible for you to abandon work. Abandoning work on the pretext that Allaah would fulfill the person’s need is a kind of absolving one’s self of responsibility on the pretext of relying on Allaah, because Allaah ordered us to take the proper means and endeavor to earn one’s living as we previously clarified.
Hence, we advise you to be moderate: you should endeavor to earn your living while striving to avoid making it an obstacle to acquiring knowledge. Indeed, Al-Bukhari entitled a chapter: “Seeking Knowledge by Turns” and he mentioned in it the story of ‘Umar with his neighbor from the Ansaar as they sought knowledge from the Prophet by turns, by one of them seeking knowledge by attending the study circles with the Prophet and then benefiting his neighbor who was busy in earning his living at that time. This proves that the Salaf (righteous predecessors) were moderate.
Moreover, you should not restrict yourself to one field of work; rather, you should search an alternative. If you fail in one kind of business, then you should try another business, or any other work than business. If you fail in doing business with your money, then you should look for another trustworthy and keen person as he might succeed in doing business with you money. If you have no money, then you should work as a hired person [employee] and so forth, as the earth of Allaah is vast and the provision of Allaah is abundant.
Allaah Knows best.
