Among the concepts in social sciences, "lifestyle" has in recent years attracted increasing attention from thinkers and researchers due to its strong connection with other concepts in this field and concurrently with the intensification of the "crisis of meaning" in modern human life. Among these, one of the most important components shaping lifestyle is having a comprehensive and systematic perspective on the category of "time," which acts as the foundation and context for realizing other dimensions of life. This research, conducted with a descriptive-analytical method and a Qur'an-centric approach, aims to explain the concept of time in the discourse of the Holy Quran and extract its implications for the Islamic lifestyle. Findings indicate that the Holy Quran, by emphasizing the temporality of human life, refers to time as an opportunity. By managing actions in light of this perspective, a fundamental transformation in lifestyle is achieved. This transformation occurs through awareness of perishability and good-deed-oriented actions. The results of this research led to the systematic extraction of time-centric lifestyle indicators based on the Holy Quran, the most important of which can be categorized into two affirmative and negative aspects: In the affirmative aspect, indicators such as "competing in good deeds," "selectiveness," "permanence and continuity," and "purposefulness" were identified. In the negative dimension, these indicators mainly focus on rejecting and avoiding behaviors such as "procrastination," "diversion," and "futility."
