Kitab Al-Kasb (Part 14): The Ranks of Earning and Their Legal Rulings.

Earning is of several ranks. The first is the level of earning which is indispensable for everyone. This means that earning by which a person can lawfully strengthen his spine in individually incumbent on everyone, for the discharge of the obligatory duties cannot be attained except by it; and that by which the discharge of the obligatory duties is attained is in itself obligatory. If he thereafter does not strive to earn more than what is necessary, he is at liberty in respect thereof, because of the statement of the Prophet, "Whoever enters upon the morning in peace over his flock and healthy in his body, having food for his day, it is as though the entire world has fallen into his possession" [Narrated by al-Tirmidhi and Ibn Majah and al-Bukhari in al-Adab al-Mufrad]....

Kitab Al-Kasb (Part 12): Is the State of Indigence Better or the State of Affluence?

This question (refer Part 11) is based on another question over which (resolution) there is disagreement among the scholars, and this (other question) is that whether the state of indigence is superior or the state of affluence? Our legal position is that the state of indigence is superior, while some of the other scholars say that the state of affluence is superior.

Kitab Al-Kasb (Part 11): Is Occupation with Earning Better or Devotion to Worship?

Thereafter another question is built upon this question (of earning), and this is that after earning what is necessary for oneself, is further occupation with earning better or devotion to worship? Some jurisprudence says, "Occupation with earning better," whereas most of our teachers are of the view that devotion to worship is better.

Kitab Al-Kasb (Part 10): Proof for the Obligatoriness of Earning up to the Indispensable Amount and Rebuttal of the Obfuscations of the Karramites in Denying It.

Our argument for this is Allah Most High's statement, "O you who have believed, spend from the good things which you have earned and from that which We have produced for you from the earth." [Al-Quran, surah al-Baqarah, verse 267]. and the command is in reality in the nature of an obligation, for giving out of what is earned cannot be conceived except after earning, and whatever which is indispensable for the discharge of an obligation is itself an obligation.

Kitab Al-Kasb (Part 8): Taking Recourse to Cause Does Not Negate Reliance.

Allah, Most High, has commanded Maryam (Mary) to shake (the trunk of) the date-palm, as He, Most High, says, "And shake the trunk of the palm toward you to let fresh ripe dates fall by you," [Al-Quran, surah Al-Maryam, verse 25] even though He is most able to provide her sustenance without her having to shake the palm and to toil, just as He has sustained her in her private chamber (or sanctuary for spiritual retreat), as He, Most Exalted, Most Glorious, says, "Whenever Zakariyya (Zacharias) went to her in he private chamber, he found supplies with her." [Al-Quran, surah Al-Imran, verse 37]. For surely, He commanded her to do that (shaking the palm) as an indication to the servants of Allah that it is proper for them not to disregard the seeking of means even if they are certain that Allah is indeed the Provider.

Kitab Al-Kasb (Part 7): Invalidating the Obfuscations of Some of the Sufis in Regard to Their Prohibition of Earning.

There is no meaning in their opposition to us in this (issue of earning) by (invoking the case of the Prophets) Yahya (John) and Isa (Jesus), blessings and peace be on them both, for we have explained that Isa, peace be on him, used to eat out of the (income generated from the) spinning of his mother, may Allah be pleased with her.

Kitab Al-Kasb (Part 6): Mention of the Arguments for the Permissibility and Commendation of Earning.

Our argument for that is the statement of Allah, "But Allah has permitted trade" [Al-Quran, surah Al-Baqarah (2): 275]. And Allah also says, "When you incur debt among yourselves" [Al-Quran, surah Al-Baqarah (2): 282], and then He says, "But let there be trade out of mutual consent from you" [Al-Quran, surah Al-Nisa '(4): 29]. And He, Most Exalted, Most Glorious, says, "Excepted is the case of a spot transaction between you" [Al-Quran, surah Al-Baqarah (2): 282].
