Is asceticism commendable, and is abandoning worldly desires, such as buying luxurious sweets and engaging in tourist travel, considered a recommended act for which one is rewarded, or is its commendability contingent upon giving charity in return, and what is the precise practical methodology for applying asceticism in all aspects of life?

Legitimate asceticism (zuhd) originates in the heart by relinquishing desire for what is of no benefit in the hereafter and trusting in what is with Allah. Outwardly, it involves abandoning superfluous matters that do not aid in obedience to Allah. As for what is beneficial in the hereafter, asceticism towards it is not part of the religion. Abandoning the examples mentioned is not considered an act of proximity [to Allah] unless it is out of preference for the poor, or to avoid preoccupation from meritorious acts. However, abandoning them by deeming them forbidden, or by absolute abstention from pleasures as an act of worship, or out of stinginess, or seeking worldly comfort — none of this is part of legitimate asceticism.
