In Jainism, the five udumbar fruits are prohibited because they are believed to harbor many tiny life-forms. The five fruits in this group are:

• Gular (cluster fig)
• Anjir (fig)
• Banyan
• Peepal (ficus species sacred fig)
• Pakar

This classification is found in traditional Jain writings and is noted in guidance on Ahimsa and diet. Some communities avoid these fruits to minimize subtle harm to living beings inside the fruits. You can read a concise note about the “udumbara fruits” in Jain dietary guidance.
