\n In the case of Imam Hussain -asws ...

\n In the case of Imam Hussain -asws , Yazeed -la Ibn Muawiya, raging in the fire of revenge for his ancestor\u2019s killings by Bani Hashim (mainly Imam Ali -asws ), was determined to destroy Islam and its people (Ahl Al-Bayt -asws ).

Imam Hussain -asws knew this and told those who wanted him -asws to stay in Medina that; \u2018no matter what I -asws do, he (Yazeed -la ) won\u2019t spare my -asws blood.\u2019 The aftermath of Imam Hussain -asws \u2019s great sacrifice was such that none of the later rulers dared to openly seek the Bayt from the rest of the Imams (4 th to 11 th Imams -asws ), but they (the Bani Ummiya and Bani Abbas Caliphs) resorted to cunningly poisoning the Imams -asws .

\n Therefore, after the Shahadat of Imam Hussain -asws , no other Imam -asws was coerced for the Bayt , except for Imam Ali Al-Reza -asws who was asked by Mamoon Al-Rashid to become his successor.

\n Imam Ali Al-Reza -asws refused but after being forced, the Imam -asws wrote: \u2018I -asws will assume this position (after you) with the conditions that I -asws will not issue any order or prohibitions nor issue any fatwa or judgment nor any appointment or dismissal of officers or change anything in the current system. You must excuse me -asws in all such matters.\u2019 Al-Mamoon agreed to all such conditions (an extract, see the complete Hadith in Appendix I).
