The ulama and jurisprudents of the Shia...
The ulama and jurisprudents of the Shia, who were so cautious in the matter of imamate, referred to him and researched as far as they could and with utmost accuracy on the matter of imamate. When they found the definite proofs on his imamate, they believed in him. They did not let themselves be carried away by passions or fancies in that, but they saw that they were responsible for that before Allah because imamate for them is one of the bases “usul” of religion.
Anyhow, the ulama and jurisprudents of the Shia asked Imam al-Hadi (a.s.), while he was yet too young, about different branches of knowledge and he answered them with answers of an expert that made them believe in his imamate. This made them more faithful and certain of what they believed that an imam must be the most knowledgeable one of his time with no difference whether young or old.
The knowledge, virtue, and delving into the sciences of the Qur’an and the Sunna of Imam al-Hadi (a.s.) astonished the minds and made meetings and sessions in all sides of the Muslim world busy talking about his unlimited scientific treasure. (3) Great numbers of Muslims believed in the imamate of Imam al-Hadi (a.s.) and found it obligatory on them to follow and obey him.
Great monies of legal dues that must be given to the imam were carried to him besides presents and donations Muslims offered to him. Investigators and policemen reported that in detail to al-Mutawakkil, the Abbasid caliph, who was the bitterest enemy of the Alawids and their followers the Shia. The caliph became so angry and was filled with grudge. He ordered Imam al-Hadi (a.s.) to be carried to “Surra Men Ra’a”.
[1] He imposed house-arrest on him there to watch all his activities, know his followers, and prevent monies from coming to him. He prevented scholars and narrators from associating with him. Imam al-Hadi (a.s.) suffered too much during the reign of al-Mutawakkil who ordered his men from time to time to search the house of Imam al-Hadi (a.s.) and carry the imam (a.s.) however he was.
Once, Imam al-Hadi (a.s.) was brought to the meeting of al-Mutawakkil while glasses of wine were here and there, songsters and songstresses sang with their musical instruments and al-Mutawakkil, the caliph, was drunken and surrounded by groups of singers and dalliers.
