The Shta knew the importance and knowledge of al- Sadiq more when he came to Iraq. That was because taqiya (protection) and the hostile authority prevented people from propagating his outstanding merits. And al- Sadiq, peace be on him, was as ‘Amru b. al- Muqdam said:” When I looked at him (al- Sadiq), I knew that he was among the descendants of the Prophets.” And as b.
Talha said in his book ‘Matalib Al- Sa’Ol’:” Looking at him reminds (the person) to refrain from the life in this world, following his behavior leads to Paradise, the light of his features bears witness that he is •mong the progeny of the Prophet, and his pure acts show that he is among the owners of the mission.aa Hushâm b. al- Hakam, who belonged to Jahnt, changed his doctrine and believed in the Imamate as a result of his discussion with al- Sadiq and his looking at him.
That looking made him full of respect for al- Sâdiq. So, he felt that such importance does not happen but for the prophets and their trustees of authority. So, among the effects of the coming of al- Sâdiq to Iraq was that he guided Hushâm, who played an important role in serving the religion and ahl al- Bayt.’[1] Among the effects of the coming of al- Sadiq to Iraq was that he built the grave of the Commander of the Faithful (Amir al- Mu’minTn- Imam ‘Ali).
And he showed it to the prominent figures of the ShT’a, for most of them did not know exactly where the grave was except that It was at Kufa in Najaf because his sons did their best to hide it to prevent the enemies of Imam ‘Au from demolishing it. So, the Shi’a began visiting it. At every visit, al- Sadiq, peace be on him, took some of his near companions with him to the grave. Also he ordered Safwan b. Mahran al- Jammal to build the grave.
In his book ‘Al- Tahdhib’, the Shaykh of the ShT’te sect Mohammed b. al- Hasan al- Tflsy has mentioned many visitations of al- Sádiq, peace be on him. Such visitations have been mentioned by Shaykh al- Kulainy, may his grave be fragrant, in’ his book ‘al- Kafi’, Sayyid b. Tawtis in his book ‘Farhat Al- GharT’, Shaykh al- Hur al- ‘âmili in his book Wasâ’il Al- ShT’a, al- Majlisi in his book ‘al- Bihar’, and the like. The following are some of the visitations of al- Sadiq and his evidence for that.
Shaykh AbO Ja’far al- Tüsy said:” Surely, al- Sadiq, peace be on him, visited the grave of Amir al- Mu’minTn, peace be on him, several times.
