Bodily worship comprises the three kinds already mentioned: it may be performed by the tongue, the limbs, or the heart. Financial worship includes acts such as paying zakat and spending in the path of Allah, for example financing jihad; Allah says, “and they strive in the way of Allah with their wealth and their selves” (Q 9:20), where wealth is cited before lives, underscoring that supporting jihad materially is an act of financial worship. The pilgrimage (Hajj) combines both forms: the rites themselves—tawaf (circumambulation), sa‘i (running between Safa and Marwa), ramy al-jimar (stoning the pillars), standing at Arafat, and the overnight stay at Muzdalifa—are bodily acts, whereas the expenses required for the journey are financial acts, for Hajj necessarily involves expenditure. (11) The shaykh offers these illustrations merely as examples, not as an exhaustive list; the acts of worship are far more numerous than those he cites and cannot be fully covered in a brief treatise. Nevertheless, he mentions representative cases. Ibn Taymiyya devoted a separate epistle, Al-Ubudiyya, to the concept of worship, its various forms, and the deviations introduced by the Sufis and others; it is a valuable work that every serious student should read.
