Al-Shaybani died in 189 A.H., and his great commentator al-Sarakhsi (d. 483 A.H.) tells us 18 that this work is the last one written by al-Shaybani.

Akasema: .Ama haikusemwa wakati wa Mtume (s.a.w.), lakini Bilal aliisikia enzi za Abu Bakr baada ya kufariki Mtume (s.a.w.) akiisema mtu ambaye hakuwa muadhini akaichukua kutokwa kwake. Akaadhini na kuitaja.
