Intellectual Accomplishments of Imam Muhammad Taqi (a.s.)
One day Imam Muhammad Taqi (a.s), then aged nine, was standing with some boys in a lane of Baghdad. Seeing the entourage of Mamun all the others ran away, but as was his habit, Imam (a.s) continued to stand at his place. Mamun came forward and asked him, “Boy! Why did you not run away?” He replied, “O Chief! The passage was not narrow. There was no expectation that you would punish an innocent person. 
Then why should I run away?” Mamun liked this explanation and he asked the name of this boy and that of his father. He said, “I am Muhammad and Imam Reza (a.s) was my respected father.” Mamun was moved by his condition and he spurred his horse forward. At that time he was going for hunting and he had some falcons with him. When he left the habitations he released a falcon to pursue a partridge. The falcon disappeared and returned after sometime carrying a small fish in its beak. Mamun was greatly astounded. On his return he found the boys playing. All ran away except Imam Muhammad Taqi (a.s). Mamun approached him and asked, “Tell me, what I hold in my hand?” He replied, “The Almighty Allah has created little fishes in the sea of His power that the falcons of the kings prey upon and inform the sons of the Ahl ul-Bayt of the Prophet.”
Ziarat of Imam Reza (A.S) with English Translation
بسم الله الرحمن الرحيم
In the name of Allah, The Beneficent, The Merciful
اَشْهَدُ اَنْ لا اِلهَ اِلا اللَّهُ وَحْدَهُ لا شَريكَ لَهُ
I bear witness that there is no God save Allah, the One; and there is no partner to share with Him. 
A Glance At The Holy Shrine of Hazrat Fatima Masumah (S.A.)
When Hadrat Fatima Masoumah (A.S.) was buried in Qum there was a shade made of straw on the holy grave built by Musa bin Khajraj. The first dome which was in the form of a tower, was built by Hadrat Zainab (A.S.), the daughter of Imam Muhammad Taqi al-Jawad (A.S.) in the middle of third century hijrah. Stone, bricks and stucco were used as construction material for this dome.
