The Prophet Said, I'm Smiled in Happiness

The Quran says whichever of the two you meet will be yours. So when it was confirmed that they are facing the army, he is happy. Why? Because he trusts Allah's promise that Allah has said, this would be yours. And now that the Muslims realize that they're facing an army and not to caravan, now the Prophet ﷺ needed to rile up the troops. He told them what do you think needs to be done? This is not the first time, no, will it be the last that we will see Shura in action. Yaddu law, yalal al-Jama'a, that Allah's hand is upon the majority or the group.
