Sa'id ibn al-'As's Tabaristan campaign (30 AH)

In year 30 Sa'id ibn al-'As campaigned into Tabaristan from Kufa; Ibn al-Athir notes it had not been raided before that year, and that men of the Prophet ﷺ's Companions were with him ².

Ibn al-Athir records the old dispute over Tabaristan's conquest: its ispahbadh had made peace with Suwayd ibn Muqarrin in 'Umar's days for a payment, and Sa'id now raided it in year 30 ². With Sa'id on this campaign were al-Hasan, al-Husayn, Ibn 'Abbas, Ibn 'Umar, Hudhayfa ibn al-Yaman (may God be pleased with him), Ibn al-Zubayr, 'Abdullah ibn 'Amr ibn al-'As and other Companions; Sa'id halted at Qumis, which was under treaty, then came to Jurjan whose people made peace for two hundred thousand, then came to Tamisa — part of Tabaristan bordering Jurjan on the sea — whose people fought him, so he led them in the prayer of fear which Hudhayfa had taught him while they fought ². He besieged them; they asked for quarter and he granted it on condition no man of them be killed — then the fort was taken and its contents seized, and Sa'id also took "Namiya," which is no city but open desert ³. Muhammad ibn al-Hakam ibn Abi 'Aqil, grandfather of Yusuf ibn 'Umar, died on the campaign; then Sa'id returned and Ka'b ibn Ju'il praised him in verse ³.
