The clashes became intense. Ammar was leading the left wing of the Imam's Army. He, though an old man, was fighting bravely.
When the sun was about to set, Ammar, may Allah be pleased with him, requested some food to break the fast.
A soldier brought him a cup full of yoghurt. Ammar became cheerful and said:
Tonight, I may he martyred because Allah's Apostle [s] has said to me:
Ammar, the unjust group will kill you, and your final drink in the world will be a cup of yoghurt.
The companion broke his fast and advanced towards the battlefield. He fought bravely. Then he fell over the ground and became a martyr.
The Imam came and sat near Ammar's head and said sadly:
May Allah have mercy on Ammar on the day when he became a Muslim, may Allah have mercy on Ammar on the day when he became a martyr, may Allah have mercy on Ammar on the day when he will be raised from the dead! Ammar enjoy your garden!
Ammar's martyrdom in the battlefield affected the course of the battle very much. The Imam's Army was in high spirits. In the meantime, Mu'awiyah's Army was in low spirits.
All Muslims memorized the tradition our Master Muhammad [s] said to Ammar bin Yasir. The tradition is as follows:
Ammar the unjust group will kill you.
All understood that Mu'awiyah and his soldiers were wrong and that Ali and his companions were right.
Thus the Imam's Army attacked Mu'awiyah's Army increasingly. Therefore, Mu'awiyah and his army were getting ready to escape.
