In Jainism there is no Agni Pooja (fire‑worship) like in Vedic/Hindu tradition.

• Rituals such as havan, homa, yajña, agni‑sanskar, agni‑puja are not prescribed in Jain Āgams or Digambar texts. ( jainknowledge.com)
• The main Jain practices are:

- Navkār Mantra, samayik, pratikraman, svādhyāy (study) - Chaityavandan, pūjā of Tirthankars (with water, chandan, akshat, dhoop, deep, etc. – Aṣṭa‑prakārī pūjā) ( jainknowledge.com) - Fasting, vows, meditation, charity, and strict ahimsā

About fire (agni) itself in Jainism:

• Fire is allowed for normal use (cooking, light, lamp in pūjā), but always with care to avoid himsā of tiny beings living in fire. ( jainknowledge.com)
• Some modern Jain families may copy homa‑style rituals from surrounding Hindu culture, but these are social or family customs, not Jain‑scriptural rituals and not required for following Jain Dharma. ( jainknowledge.com)

So, Jainism has pūjā with lamp (dīpak) as one item in Aṣṭa‑prakārī pūjā, but no separate “Agni Pūjā” or fire‑sacrifice ritual as part of authentic Jain religious practice.
