Can some one please write Surah and # of an Ayah revealed to Prophet Mohammad SAW after Battle of Uhud?

While the arrows keep coming towards Holy Prophet, he got wounded, became unconscious and fell on the dead, who had lost their lives in his defense. When the enemies saw Mohammad unconscious they thought that he has died and withdrew from the battle field.

After a while, the Prophet returned to consciousness and his army escorted him to the foot of the hill. The leader of the Meccan army declared victory over Muslims and shouted the death of Mohammad and his commanders. When Abu Sufyan the Meccan Chief declared “The End to Islam”, The Prophet could not tolerate the insult on Islam; he with others shouted back saying “ God alone is Great and Mighty. God alone is Great and Mighty. He alone is High and Honored. He alone is High and Honored”.

The Prophet collected the wounded and the dead. The wounded were given first aid and the dead were buried. This battle showed love, care, devotion and sincerity of Muslims among themselves.

The Ayat revealed was

"Your misfortune on the day the two hosts met was by God's permission, so that He might distinguish the believers from the hypocrites. It was said to them, 'Come, fight for God, or defend yourselves'. They said, 'If we knew fighting (sc. with a hope of success, or, would actually take place), we would have followed you'. They are thence closer to unbelief than to belief. They speak out with their mouths what is not in their hearts, but God knows what they conceal. Those who remained back and said about their brethren, 'If they had obeyed us, they would not have been killed.' Say, 'Then prevent death from yourselves, if you should be truthful'
