In the name of Allah most gracious most merciful
Assalaamu alaykum wa rahmatuallahi wa barakatuhu

I have resolved to die this very hour
 

Said ibn Zayd was totally devoted to the Prophet and the service of Islam. He witnessed all the major campaigns and encounters in which the Prophet engaged with the exception of Badr. Before Badr, he and Talhah were sent by the Prophet as scouts to Hawra on the Red Sea coast due west of Madinah to bring him news of a Quraysh caravan returning from Syria. When Talhah and Said returned to Madinah the Prophet had already set out for Badr with the first Muslim army of just over three hundred men.

After the passing away of the Prophet, may God bless him and grant him peace, Said continued to play a major role in the Muslim community. He was one of those whom Abu Bakr consulted on his succession and his name is often linked with such companions as Uthman, Abu Ubaydah and Sad ibn Abi Waqqas in the campaigns that were waged. He was known for his courage and heroism, a glimpse of which we can get from his account of the Battle of Yarmuk. He said:
"For the Battle of Yarmuk, we were twenty four thousand or thereabout. Against us, the Byzantines mobilized one hundred and twenty thousand men. They advanced towards us with a heavy and thunderous movement as if mountains were being moved. Bishops and priests strode before them bearing crosses and chanting litanies which were repeated by the soldiers behind them.

When the Muslims saw them mobilized thus, they became worried by their vast numbers and something of anxiety and fear entered theft hearts. Thereupon,
Abu Ubaydah stood before the Muslims and urged them to fight. "Worshippers of God" he said, "help God and God will help you and make your feet firm."
"Worshippers of God, be patient and steadfast for indeed patience and steadfastness (sabr) is a salvation from unbelief, a means of attaining the pleasure of God and a defence against ignominy and disgrace."

"Draw out your spears and protect yourselves with your shields. Don't utter anything among yourselves but the remembrance of God Almighty until I give you the command, if God wills."
"Thereupon a man emerged from the ranks of the Muslims and said: "I have resolved to die this very hour. Have you a message to send to the Messenger of God, may God bless him and grant him peace?"
"Yes" replied Abu Ubaydah, "convey salaam to him from me and from the Muslims and say to him: O Messenger of God, we have found true what our Lord has promised us."

"As soon as I heard the man speak and saw him unsheathe his sword and go out to meet the enemy, I threw myself on the ground and crept on all fours and with my spear I felled the first enemy horseman racing towards us. Then I fell upon the enemy and God removed from my heart all traces of fear. The Muslims engaged the advancing Byzantines and continued fighting until they were blessed with victory."

Allah Knows Best
