After Muslim ibn Aqil was martyred, Muhammad and Ibrahim were also arrested and put into a dungeon.
It is said that Muhammad was just eight years old and Ibrahim was just less than seven years old (according to Book Majalis al-Muntazirin, Volume#1, Page#261) On the 12th of Dhu al-Hijjah in 60 Hijra, when the jailer came to give the children their evening meal, he saw them saying their prayers.
Everywhere they went, they found the roads blocked by Ubayd Allah ibn Ziyad's soldiers.
Unfortunately my husband Harith is working for Ubayd Allah ibn Ziyad.
You can rest in the spare room but make no noise otherwise when he comes back, he will find out you are here".
On learning they were the sons of Muslim ibn Aqil, he tied both the boys to a pillar.
Harith wanted to collect the reward which Ubayd Allah ibn Ziyad had offered to anyone capturing the children.
Ibrahim said, "In that case, give us time to finish our Fajr prayer."
Give our mother courage when she hears of our death and judge between us and our killers!"
The two innocent children of Muslim ibn Aqil that were killed brutally near the river of Euphrates, are supposed to be buried near the town of Musayyib, Babil Governorate, Iraq.
