In Baghdad, al-Kulaynī lived in the south-western quarter of Darb al-Silsilah and hence is also at times referred by the title ‘al-Silsilī’ in some sources. He passed away in Baghdad in either 329 AH (according to al-Najāshī and al-Ṭūsī in his Rijāl) or in 328 AH (according to al-Ṭūsī in his Fihrist and ʿAlī ibn Ṭāwūs in Kashf al-Maḥajjah). The former date is generally accepted over the latter. He apparently died in the month of Shaʿbān and this is of special interest since the final representative of the 12th Imām (a) in the minor occultation, al-Samurī, also died in exactly the same month and year. Al-Kulaynī’s grave is also a point of disagreement and in some older sources it is said that he was buried in the Bāb al-Kūfah cemetary. This is what Ibn ʿAbdūn, the erstwhile Imāmī scholar (d. 423) says when he recounts visiting al-Kulaynī’s grave only a few decades after his demise and seeing a tombstone on which was carved the name of al-Kulaynī and his father. However, it is reported that the site of his grave was later forgotten or lost (possibly due to flooding).
2 However, there is a tomb in Baghdad that is said to belong to al-Kulaynī and is visited by many Shiʿas today, but it is located in a different area of the city, an area that was predominantly Sunnī in the past.
