salamualekum–There are few difference that Bibi sakina and Bibi Rukhaiya are the same– there is circle of people who believe that Bibi sakina lived a complete life while Bibi Rukhaiya died very young– Pl clarify — shukriya

Walaikumussalam
Yes the one who martyred in young age according to most of the historian was Hazrat ruqaiya
Wassalam
