The Abbasid Caliphate had always been under the protection of the Bani Hashim and this was the reason why Haroon, like the Mahdi, was afraid of Imam Musa Kazim in his time and had to spend most of his life in captivity. Aaron also feared that his popularity among the people could lead to a revolt at any time. On the other hand, some of the people close to the Imam were afraid of him and they kept informing Haroon that the Imam was collecting Khums and there could be a revolt at any time.
Haroon Rashid’s wife Zubeida Khatun was a very religious and knowledgeable woman. In his palace, a thousand captives were engaged in reciting the Qur’an 24 hours a day. Zubeida Khatun, the wife of Caliph Harun al-Rashid, once came to Mecca to perform Hajj. There was a shortage of water in those days and the pilgrims were especially distressed. When they saw the people of Makkah and the pilgrims suffering from water problems, they were very saddened, so they decided to dig a great canal at their own expense. By giving the order, he performed a great deed which will be remembered by the world.
Expert engineers from different areas were called in to plan the canal excavation. According to the engineers’ plan, a canal was planned to be constructed from Haneen Valley, 35 km northeast of the border. Seventeen million dinars were spent on this great project. When the planning of the canal Zubeida started, the engineer in charge of the project came and said, “The canal you have ordered requires a lot of money, because to complete it you have to cut big mountains, ups and downs.” Will have to deal with the difficulties and hundreds of workers will have to work day and night then the project can be completed somewhere.
On hearing this, Zubeida said to the engineer: Start this work, even if it costs one dinar on one stroke of the ax. Thus, when the canal project was completed, the organizers and caretakers presented the details of the expenses in the service of the queen. ۔ At that time the queen was in her palace on the banks of the river Tigris. The queen took all the papers and carried them into the river without opening them and said: O Allah! Do not hold me accountable on the Day of Resurrection even if I have not taken any account in this world
