The author of the book "The moon of Bani Hashem" mentioned that Um Al-Baneen (peace be upon her) has seen the Commander of the Faithful (peace be upon him) one day, putting Aba Al-Fadl (peace be upon him) on his thigh, uncovered his arms, kissed them and cried.

She (peace be upon her) was surprised to see a boy with Alawi virtues when his father looks at him cries without a reason, but Imam Ali (peace be upon him) told her the secrets of what will happen to his hands that will cut in the support of his brother Al-Hussayn (peace be upon him) so she also cried very loud. In fact, on the birth of Al-Abbas (peace be upon him) the House of Imam Ali (peace be upon him) was filled with joy for the coming of this new born who will be a hero, and with grief and tears for the cutting of his hands and his killing in the future in Karbala.

Imam Ali (peace be upon him) then told Um al-Baneen (peace be upon her) that for Abbas’s great sacrifices, God will grant him an unparalleled rank that all martyrs will wish for if they had its like, including the great martyrs Hamza Ibn Abd al-Muttalib and Ja'far Ibn Abi Taleb, who wish they had his position and rank bestowed to him by the Almighty on the day of resurrection, for the uncountable sacrifices, chivalry and altruism in Karbala…
