The series is based on the life of Imam Ali ibn Musa ar-Reza (AS).

Serial based on the life of Imam Ali bin Mousa al-Reza (PBUH), the eighth Imam of Shiites , He is of the progeny of Prophet Muhammad (swas) and his eighth successor. At age 35 after the Martyrdom of his father, Imam Musa al Kadhim, he became the leader of the Islamic Ummah. His life was contemporary to the Abbasid reign and therefore, he suffered great difficulties made by the Abbasids. Finally, he was martyred by Ma'moon (the contemporary Abbasid Caliph) at the age of 55.

Imam Reza's (PBUH) Imamate can be divided into three periods:
1-The first ten years was contemporary to Haroon's caliphate.
2-The next five years was contemporary to Amin's caliphate.
3-The last five years was contemporary to Ma'moon's caliphate.

It was during the first period that great disasters, especially the martyrdom of Imam Kazem (PBUH), happened to the Alavi people (the children of Imam Ali (PBUH)). Haroon was instigated to kill Imam Reza (PBUH), but had not found the opportunity. After Haroon, Amin became the caliph. At that period, the government was weakened. Amin was drowned in his corruption and paid no attention to Imam and his followers. This period was peaceful for Imam and his followers.

However, Ma'moon killed his brother, Amin, and became the caliph. He suppressed the objectors and gained the control of all the Islamic countries. He gave the leadership of Iraq to one of his agents and settled in Marv. He then chose Fazl ibn Sahl, who was a great politician, as his minister. But the Alavi people were a threat to his government. After suffering murder, plunder and torture for a century, they had found the opportunity to object the government and to overthrow it. They were successful in gaining people's support, because they also had suffered great losses from the Abbasid Caliphate. Therefore, Ma'moon decided not to confront them and wanted to bring back peace and security to strengthen his government.

So, after consulting Fazl, he came up with a treacherous plan. He decided to offer the caliphate to Imam Reza (PBUH) and withdraw himself. Because whether the Imam accepted or not, it would still be a victory for Ma'moon. If Imam accepted, and became Caliph allowing for Ma'moon to be the vice-caliph, that would guarantee the legitimacy of Ma'moon's government. Thus Ma'moon decided to force the position of Caliph on Imam. It was then easier for him to eliminate Imam Reza (PBUH) and become the legal leader. In this case, the Shiites would consider his government to be legitimate and would be satisfied with it and accepted him as Imam's successor. Furthermore, the risings made against his government would lose their attraction and legitimacy.

However, if Imam didn't accept the caliphate, he would then oblige Imam to be his successor and guarantee the legitimacy of his government through this to weaken the uprisings. On the other hand, he could make Imam settle near himself to control Imam and suppress his followers. In addition, Imam Reza's (PBUH) Shiites and followers would criticize him for not accepting the caliphate and he would lose his respect among them.

"Wilayat e Ishq" portrays in detail how Imam doesn't let Ma'moon succeed in this plots.
