In view of the large number of religious schools hosted by the holy city of Karbala at the beginning of the thirteenth century of the Hijra (nineteenth century AD), and the emergence of many different jurisprudence ideologies by these schools, the Ottoman authorities used this difference as a pretext for the complete reoccupation of the city.

One of the signs of that Ottoman scheme is the mobilizing of large military forces by the local governor "Mohammad Najib Pasha" in order to besiege Karbala using the dispute between the followers of the "Sheikhi" school and "Kashfi" school, as well as taking advantage of some of the heads of sedition who came from outside the city to incite on taking up arms and to confront all those who disagree with them, even with thoughts, which eventually gave the foreign forces an execuse to take the city by force and practicing murder and looting in a way that the population has never seen before.
In the face of these new developments, the religious scholars have called on Karbala citizens to displace to the holy shrines of Imam Hussein and his brother Abbas "peace be upon them", as the city's elders and elders held continuous meetings in the two holy shrines in preparation for the appropriate response against the invading forces.
