After prophethood he wept at her grave.

The Prophet's relatives

He was an uncle and foster-brother of the Prophet (pbuh), and only two years older than him.
He was a warrior and sportsman and had little interest the issues of Makkah.
He hit Abu Jahl on the head when he heard Abu Jahl had assaulted the Prophet and asked him to hit him back if he was brave enough.
Hamza then declared that he had become Muslim.
It gave the Muslims a lot of strength and they were able to pray in public.
He was also sent as a leader of an expedition to seashore and was the first Muslim to be given a flag.
In the battle of Badr he killed leading men of the Quraysh including Hind’s father Utbah; she vowed revenge and hired Washi to kill Hamza which he did at the battle of Uhud.
He was given the title “Chief of Martyrs”, and the Prophet led his funeral prayer.

He was a prominent and powerful figure among the Quraysh, and a staunch opponent of the Prophet and the Muslims.
It was his caravan returning from Syria that was the basis for the battle of Badr, and candidates could give details of his involvement in this event.
After the loss at Badr, revenge was sought and Abu Sufyan led the Quraysh army to Uhud.
