To navigate a conflict between members with differing interpretations of Islamic law within an Islamic organization, a leader should:

1. **Listen to All Sides**: Give each party an opportunity to explain their perspective without interruption, ensuring everyone feels heard and respected.

2. **Seek Common Ground**: Identify areas of agreement between the differing interpretations and build on them to foster unity.

3. **Consult Islamic Scholars**: Involve knowledgeable scholars or a council of diverse scholars to provide authoritative guidance on the matter, ensuring decisions are rooted in sound Islamic jurisprudence.

4. **Promote Tolerance**: Emphasize the importance of respecting differing valid opinions within Islamic law, recognizing that diversity of thought has always been a part of Islamic tradition.

5. **Encourage Dialogue**: Facilitate open and respectful dialogue between the parties, allowing them to express their views and understand each other better.

6. **Educate on Principles of Ijtihad**: Highlight the concept of Ijtihad (independent reasoning) and the legitimacy of multiple interpretations, helping members appreciate the depth and flexibility of Islamic law.

7. **Remain Neutral and Fair**: As a leader, maintain neutrality and fairness, avoiding favoritism, and making decisions that prioritize the welfare and unity of the organization.

8. **Focus on the Greater Good**: Encourage members to prioritize the unity and goals of the organization over individual differences, reminding them of the broader mission they share.

9. **Invoke Islamic Ethics**: Ground the resolution process in Islamic principles of justice, compassion, and wisdom, ensuring that the approach is both ethical and effective.

By taking these steps, a leader can navigate conflicts effectively, promote mutual respect, and strengthen unity within the organization.
