The idea of tafaqquh as a way of reviving fiqh sees fiqh as deep understanding that moves from meaning to operational definition and finally to grounded policy. Its framework combines scriptural text and the objectives of sharia (maqasid) with a methodological cycle of tasawwur, ta‘rif, ta‘lil, tatbiq and taqwim. The approach is applied to three contemporary problems: waste management, digital finance for zakat, infaq and sadaqah, and the ethics of artificial intelligence in academia. Its aim is an ecosystem of trust that is just, sustainable and protective of the dignity of knowledge.
