Umm Salamah:
During the battle of the Camel, the Mother of the Believers Umm Salamah (ra) sent her son ‘Umar Ibn Abi Salamah to ‘Ali with the message: “By Allaah, he is dearer to me than my own self; he will go out with you to fight alongside you.” He went out with ‘Ali (ra) and remained with him. [Ansaab Al-Ashraf, 4/224]
Mu’aathah, the wife of Silah:
Silah Ibn Aktam told his son: “O my son, go ahead and fight!” His son went ahead and was killed. Later on Silah himself was killed. When Mu’aathah the wife of Silah received the news of the death of both her husband and son, she told the woman who came to give their condolences: “If you are coming to congratulate me then welcome. If you are here to give me condolences then you must leave!” [Siyar A’laam An-Nubula, quoting from “Mashari Al-Ashwaq Ilaa Masari Al-Ushaaq” by Ibn Nuhaas]
Al-Khansa’ Bint ‘Amr:
The Battle Of Qaadisiyyah (14H) which occurred during ‘Umar Ibn Al-Khattaabs reign lasted for four days. On the second day of the battle, Al-Khansa’ Bint ‘Amr urged her sons to fight. In the Muslim women’s camp in Al-‘Udayb, Al-Khansa’ Bint ‘Amr – the poetess of Banoo Sulaym whose career straddled the jaahiliyah and Islaam – sat with her four grown sons, urging them to fight. She said, “You became muslim willingly and migrated by choice. You know what Allaah has promised of great reward to the Muslims who fight the kaafirs, and you know that the realm which abides is better than the realm which will pass away. Allaah says, ‘O you who believe! Endure and be more patient [than your enemy], and guard your territory [by stationing army units permanently at the places from where the enemy can attack you], and fear Allaah so that you may be successful.‘ [3:200] If you wake up safe and sound tomorrow, inshaaAllah, then go and fight your enemy, seeking Allaah’s support against His enemies. When you the fighting grow tense, then go forth. If you do that, you will gain booty and honour in the Hereafter.”
Umm Haarithah:
Haarithah was killed during the battle of Badr by a stray arrow. Anas narrated that the mother of Harithaah came to the Messenger of Allaah and asked him, “O Messenger of Allaah, won’t you tell me about my son Haarithah? If he is in Paradise I would be patient. If he is not I would cry for him.” The Messenger of Allaah said, “Have you lost your mind?! It is not one Paradise but many, and your son is in the highest one: Al-Firdous!” [Bukhaaree]
