Composed largely during the years 333-36AH/945-48CE, Ja‘far's poetry expressed intense loyalty toward Fāṭimid rule. Many of his compositions also contained allegorical interpretations or ta'wīl for Qurʾānic words and expressions (Sarā'ir al-nuṭaqā and Asrār al-nuṭaqā) as well as Islamic ritual worship, letters of the Arabic alphabet (Risālat ta'wīl ḥurūf al-muʿjam) and the hierarchy of the Fāṭimid daʿwa (Kitāb al-kashf, al-Shawāhid wa-l-bayān and Kitāb al-farā'iḍ wa ḥudūd al-dīn).[7]
