After Hazrat Fatima Zahra (sa), Hazrat Zainab (sa) is the unique hero amongst the women in the history of Islam. With her brave and outstanding character, her deep faith, and her strong belief in Allah (SWT), she had a significant role in protecting religion on its original path.

Hazrat Zainab (sa) is the message bearer of the martyrs in Karbala and the companion of Imam Hussain (as) in the important rising of Ashura. Her virtues were to such an extent that she was given titles by these meanings: the wise woman of (the tribe of) Bani Hashim, the trustworthy, the knowledgeable, the virtuous, and the ideal.

Her name always follows the name of Imam Hussain (as). Shiite historians have recognized her as the second most significant character in the tragedy of Karbala. More importantly, her role in the tragedy had great impact in keeping the movement of Ashura alive. Hence, historians consider Hazrat Zainab (sa) as the key to the victory Imam Hussain's (as) rising.

Imam Hussain (as) would show great respect for Hazrat Zainab (sa) when she would come to see him. Hazrat Zainab (sa) has narrated many sayings from her grandfather Prophet Muhammad (saw), from her father Imam Ali (as), and from her mother Hazrat Fatima Zahra (sa). Hazrat Zainab (sa) had a strong heart and eloquent language. She was brave, ascetic, pious, modest and very courageous. When Imam Hussain (as) denied paying allegiance to Yazid son of Muawiya, he left the city of Medina to go to Makkah. Hazrat Zainab (sa) accompanied him with her two children.

She devoted herself to the movement of Imam Hussain (as). She supervised the captives of the caravan after Ashura, took care of patient of Karbala (Beemar-e-Karbala), Imam Sajjad (as) when he was ill, and revealed the true evil character of the Umayyad Dynasty through her sermons. After the event of Ashura and during her stay in Damascus and Kufah as a captive, she delivered a number of sermons, which informed people of the true face of the Umayyad Dynasty and which, also became the key to the remembrance of Ashura for future generations. Moreover, when she went back to Medina, she continued to reveal the evil character of the Umayyad Dynasty by reminding people of the martyrs of Karbala. She was so patient that she became known as the "The Hero of Patience".
