Epithets expressed the high qualities he had

His epithets expressed the high qualities he had. His epithets are as follows:

1. An-Nasih (loyal); he was called so because he was the sincerest advisor to the nation.

2. Al-Mutawakkil (reliant on Allah); he disliked this epithet and ordered his companions not to call him with it. I think he hated this epithet because it was the epithet of the Abbasid caliph Ja’far al-Mutawakkil who had bitter grudge, spite, and enmity towards the Ahlul Bayt (a.s.).

3. At-Taqiy (pious, devout); he was called so because he feared Allah and turned to Him. Al-Mutawakkil, the tyrant Abbasid caliph, tried his best to attract Imam al-Hadi (a.s.) to the fields of amusement and debauchery but he failed.

4. Al-Murtadha (being pleased with by Allah); it was his most famous epithet. 

5. Al-Faqeeh (jurisprudent); he was the most aware of his age in jurisprudence and he was the authority that jurisprudents and scholars referred to.

6. Al-Aalim (knowledgeable); he was the most knowledgeable one of people at that time not only in the Islamic laws, but all branches of knowledge and sciences.

7. Al-Ameen (trustee on religion and life)

8. At-Tayyib (generous, good-hearted, good-natured…)

9.  Al-Askari (military); he was called so because he resided in Surra Men Ra’a (Samarra’) which was called al-Askar.[1]

10. Al-Muwadhdhih (explainer of the verdicts of the Holy Book and the Sunna)

11. Ar-Rasheed (wise, prudent); he was called so because he was the wisest and most prudent of his time.

12. Ash-Shaheed (the martyr) because he was martyred at the hands of the enemies of Allah.

13. Al-Wafiy (loyal); he was the most loyal of his people, and loyalty was an element of his personality.

14. Al-Khalis (pure from every defect and bad)
