He was one of the Imams whom the Shiite exaggerators believe to be infallible like prophets…’.(4) 2. Al-Yafi’iy: Al-Yafi’iy says, ‘Imam al-Hadi (a.s.) was worshipful, jurisprudent, Imam…’.(5) 3. Abul Fida’: He says, ‘Ali at-Taqiy (pious) is one of the twelve Imams of the Shia. He is Ali az-Zakiy bin Muhammad al-Jawad…’(6) 4. Ibn as-Sabbagh al-Maliki: He says, “Someone of scholars said, ‘The virtue of Abul Hasan has established its domes on the galaxy, and stretched its ropes on the stars.
No excellence is counted, unless with him is its conclusion, and no nobility is mentioned, unless with him are its details and totality, and no high quality is regarded, unless his proofs appear on it. He deserved all that due to the essence of liberal qualities that he alone had, and glory that governed his lofty nature which was purified from any blemish, and so his nature and morals were pleasant, his conduct was fair, and his qualities were virtuous.
His gravity, calmness, certainty, chastity, honesty, and wit were like the Prophet’s and Ali’s. He had a pure soul and high determination such that no one among men resembled him (in this respect), and he lived a coarse life of asceticism such that no human participated with him in it or looked forward to it.’(7) 5. Ibn Shahrashub: He says, ‘He (Imam al-Hadi) was the best and most truthful of people. He was the cleverest from near and the most perfect from far.
When he kept silent, dignity was observed on him, and when he spoke, splendor was observed on him. He was from the house of prophethood and Imamate, and the abode of guardianship and caliphate. A branch from the lofty tree of prophethood was he, and a fruit from the tree of the mission was he…’(8) 6. Al-Qutb ar-Rawandi: He says, ‘As for Ali bin Muhammad al-Hadi, all qualities of Imamate have gathered in him. His virtue, knowledge, and good merits have been perfected.
All his morals were extraordinary like the morals of his fathers. He spent the night worshipping, facing the Qibla, wearing a wool garment and sitting on a mat. If we mention his high qualities, the book shall be prolonged with them.’(9) 7. Ath-Thahabi: He says, ‘Ali bin Muhammad bin Ali bin Musa bin Ja’far bin Muhammad bin Zaynol Aabidin bin as-Sayyid ash-Sharif al-Alawi al-Husayni was jurisprudent and one of the twelve Imams. The Twelver Shia call him al-Manari.’(10) 8.
Ibn Hajar: He says, ‘Ali al-Hadi was the heir of his father’s knowledge and generosity.’(11) 9.
