33 Of course, it goes without saying that these differences are with respect to voluntary actions, while obligatory actions are required of everyone. Jamaal Zarabozo writes, “This reality is all by the mercy of Allah. Beyond the obligatory deeds, people are free to pursue those good voluntary deeds that they are most attracted to. There are so many areas of voluntary deeds that it seems inconceivable that a person could not find some voluntary deed or deeds that he would like to perform in order to get closer to Allah. Allah’s path to paradise is wide enough to accommodate all of those different leanings. However, this is all dependent on the individual first fulfilling, in general, the obligatory deeds. If the person does not do that, then he may not be on the straight path at all.” Jamaal Zarabozo,

37 The term
aḥkām is not used here in its narrow jurisprudential usage to refer to legal rulings but rather linguistically to describe knowledge-related judgments. Being oriented towards
aḥkām entails a pragmatic approach and focuses on structure, decisions, good versus bad, true versus false, etc.

ḥasan (fairly authentic) according to Ibn Ḥajar al-ʿAsqalānī. The Prophet ﷺ gave this advice to Wābisa ibn Maʿbad and very similar advice to Nawwās ibn Samʿān (
Ṣaḥīḥ Muslim, no. 2553a). Ibn Ḥajar al-Haytamī (d. 974 AH) makes the interesting observation that this advice applies to those persons similar to Wābisa who possess that faculty of inner perception (
idrāk), while others may need more explicit religious rulings of commands and prohibitions, and thus the Prophet addressed everyone with the advice most suited to them. See al-Haytamī,
Fatḥ al-mubīn (Dār al-Minhāj, 2008), 465. Judgment-oriented people may need objective definitive rules to avoid succumbing to personal bias (
hawāʾ) and desires (
shahawāt).

43 It might strike some as paradoxical for experience-oriented individuals to have an aptitude for highly theoretical subjects. However, it is their intuitive capacity that enables them to transform the seemingly theoretical into a strong lived experience. People with this approach to knowledge are also not content with merely learning what is; they want to know why it is. They have a strong need for true understanding and a recognition of the wisdom in the rulings and rituals of Islam. This goes back to their desire for experience. Without understanding the wisdom, it is hard to experience what is intended by those religious practices.

The repeated commission of this sin was not interpreted as evidence of a lack of faith. Rather, it was clear that this particular individual had an addiction alongside his strong love for Islam.
54 Allah’s Messenger ﷺ said, “O ʿAbdullah! Have I been informed that you fast all day and stand in prayer all night?” I said, “Yes, O Allah's Messenger ﷺ!” He said, “Do not do that! Observe the fasts sometimes and also leave them [the fasts] at other times; stand up for the prayer at night and also sleep at night. Your body has a right over you, your eyes have a right over you, and your wife has a right over you.”

There is also a historical discussion amongst the classical scholars on whether it is worse to do something prohibited or to abandon something obligatory. The former was stated explicitly by Imām Aḥmad (d. 240 AH), as noted by Ibn Rajab in
Jāmiʿ al-ʿulūm, and is the position of the majority as noted by Ibn Ḥajar al-Haytamī in
Fatḥ al-mubīn. Meanwhile, the latter is the opinion of Imām Sahl al-Tustarī (d. 284 AH) and advocated by Ibn Taymiyya and Ibn al-Qayyim in
al-Fawāʾid. The reality is that both sides have strong arguments and evidence in their favor and are easily reconciled with reference to the concept of spiritual personality such that it may depend on the person in question and their individual weaknesses.

Rather, gathering all of the fears a person may have about the world and recognizing that only Allah is capable of benefit or harm naturally dissipates their fear of this world. Fear of Allah alone becomes a source of immense courage, as a person recognizes that nothing in this world can harm them without the permission of Allah.

72 There is an established concept in psychology referred to as “moral self-licensing,” whereby a person’s past good deeds make them feel entitled to indulge in desires or make excuses for unethical behavior.

74 It is important to distinguish between healthy shame (
hayaʾ) (i.e., “I did something wrong”) that helps one to avoid bad, and toxic shame (i.e., “I am a bad person”) where one views oneself with contempt and unworthy of any good, falling into despair (
al-ya’s), effectively denying the power of God’s mercy to reach oneself.

92 The Qur’an actually mentions this combination in 38:45 and mentions Prophet Ibrahim as an example. His strong vision (
baṣīra) and powerful pursuit of good (
ayd) play out multiple times in his life. It is what gave him the resolve to withstand the persecution of his people and trust that his family would grow and prosper in the barren valley of Mecca. We also find a strong drive for action as he built the Kaʿbah with his hands, and he physically broke the idols as part of his preaching. The Prophet Muhammad ﷺ likened Abu Bakr to Ibrahim and ʿIsa, while he likened ʿUmar to Nuh and Musa as reported in
Musnad Aḥmad.
93 The Messenger ﷺ asked, “Who is fasting today?” Abu Bakr (rA) replied, “Me.” The Messenger ﷺ asked, “Who has followed a funeral procession today?” Abu Bakr replied, “Me.” The Messenger ﷺ asked, “Who has fed a poor person today?” Abu Bakr replied, “Me.” The Messenger ﷺ asked, “Who has visited a sick person today?” Abu Bakr replied, “Me.” The Messenger ﷺ then said, “Any person that has done these four things in one day will enter Paradise.”
