â€˜AlÄ« Ibn Husayn Ibn â€˜AlÄ« Ibn AbÄ« TÄlib, known as SadjdjÄd, the fourth Shiâ€˜ites ImÄm, was as maintained in one narration born in 38A.H. and poisoned by WalÄ«d Ibn â€˜Abd al-Malik in 94 A.H.
 If the narrated date of birth be true, ImÄm should have evidently perceived both ImÄm â€˜AlÄ« and ImÄm MudjtabÄ as well as ImÄm Husayn (a) and realized how Muâ€˜Äwiya had been exercising pressure on the Shiâ€˜ite Muslims living in Iraq and other lands. In the light of the reports narrated from the event of Taff (KarbalÄ) a number of writers concluded that ImÄmâ€™s age must have been less than what reported ands his year of birth had been 48. Such reports forebode that following ImÄm Husaynâ€™s martyrdom some were determined to assassinate ImÄm SadjdjÄd (a) also, but they were impeded due to his immaturity.
Humayd Ibn Muslim, present in KarbalÄ, said, â€œWhen Shimr came to kill ImÄm SadjdjÄd, I dissuaded him saying he was a little boyâ€.
Found in another version when â€˜Ubayd AllÄh decided to murder ImÄm SadjdjÄd (a), he commanded to examine the signs of his maturity. After they attested to it, he issued the verdict of his murder. Notwithstanding, ImÄm managed to change his mind by saying him â€œIf you claim that you are from among the Prophteâ€™s kins (as AbÅ« SufyÄnâ€™s grandson), you are obliged to let a man accompany these women to Medinaâ€.
It is also quoted that Zaynab (a) averted ImÄm SadjdjÄdâ€™s murder saying â€œkill me first if you want to kill himâ€.
 Enumerating the Umayya atrocities, DjÄhiÂ¨ has alluded to their irreverence about ImÄm SadjdjÄd (a) by checking the signs of his maturity after the event of KarbalÄ.
