The Establishment of the Day of the Cave in Baghdad as a Counterpart to the Day of Ghadir

استحداث يوم الغار ببغداد مقابلاً ليوم الغدير

c. 21 November 999 CE · 26 Dhu al-Hijja 389 AH

Baghdad

The custom of the Shi'a of al-Karkh and Bab al-Taq was to raise domes, hang cloths and display decorations on the day of Ghadir, kindle fire on its eve and slaughter a camel on its morning. The other group wanted to do something in response, so it claimed that the eighth day of that month was the day on which the Prophet ﷺ and Abu Bakr were in the cave, and it did with that day what the Shi'a had done. Opposite the day of Ashura it set a day eight days later, attributing it to the killing of Mus'ab ibn al-Zubayr, and its people visited his grave at Maskin as the grave of al-Husayn is visited. The Day of the Cave began on Friday, four days before the end of Dhu al-Hijja in the year eighty-nine. 1

Summary

In the year 389 AH a celebration described as an innovation (bidʿa) was introduced in Baghdad and named "the Day of the Cave" (Yawm al-Ghar). The common people (al-ʿamma) made it a counterpart to the Day of Ghadir, which the Shiʿa celebrated in Karkh and Bab al-Taq. 1

The counter to the Day of Ghadir

Ibn al-Jawzi reports that it had become the custom of the Shiʿa of Karkh and Bab al-Taq to set up domes, hang cloths and display decorations on the Day of Ghadir, to light fires on its night and to slaughter a camel on its morning. The other group wanted to answer this, so they claimed that the eighth day from the Day of Ghadir was the day the Prophet was in the cave with Abu Bakr, and they did on it the same as the Shiʿa did on the Day of Ghadir. 2

The Day of Musʿab

They set against ʿAshura a day eight days after it, attributing it to the killing of Musʿab ibn al-Zubayr; they visited his grave at Maskin as the grave of al-Husayn is visited. The Day of the Cave began on a Friday, four days before the end of Dhu al-Hijja. 2

The Nizamiyya Madrasa of Baghdad

The Nizamiyya of Baghdad, first and most famous of the madrasas founded by the vizier Nizam al-Mulk al-Tusi: building began in 457 and sisters rose at Nishapur, Isfahan, Herat, Basra, Mosul and Amid; the Imam al-Haramayn al-Juwayni then Abu Ishaq al-Shirazi taught in it, and it mothered the Sunni institutional model that the later madrasas of Baghdad followed — the caliphs prayed there and Nizam al-Mulk himself visited to inspect its library.
