Today hadees of the day
Imam Jafar Sadiq (as) has said :
“One who recites the Tasbeeh of Hazrat Zahra (s.a.) after a wajib namaz before he stretches out his legs ( i.e. he recites the Tasbeeh while he is in the posture of Tashahud) , then Jannat becomes wajib upon him”
(Falaahus Saael by Ibne Taaoos (r.a.), Pg. 165
