Hazrat Umm ul-Banin (peace be upon her) ("mother of several sons") was at the highest peak of obedience to Wilayat (guardianship) who sacrificed his sons to defend the Wilayat. According to historical sources, after hearing the news of the martyrdom of her sons in Karbala, the only sentence she repeatedly said was this:" my sons and whatever is under the sky be sacrificed for Imam Hussein (peace be upon him), and when she got wind of the martyrdom of Imam Hussien, she let out a deep sorrowful sigh and said: my heart is broken into pieces.
