This group is named Mustaali because they follow Imam Mustalli, after Imam Mustansir Billah, and not Nazaar whom the Aga Khan group consider as their Imam. Later on this group was referred to as the Tayaabi group as named after the last known Imam Tayaab. The group currently follows the current Imam who is from the progeny of Imam Tayaab. This group was later on divided into Sulaimani and Dawoodi Bohras. The Sulaimani prefer to call themselves as Sulaimani after their 27th Dai Sulaiman bin Hassan.
