I had hoped that someone else had created this topic instead with information etc...

But the 17th of Ramadan (which is either today or yesterday depending on when people started ramadan) is the date for the battle of Badr.

In this battle 313 Muslims faced off with approximately a thousand people from the Quraysh who had to come to defeat them.

This was a year after the prophet (saw)'s migration to Madinah and the muslim cmmunity was at a feotal state - where if Muslims had lost this war, they would not have survived to tell the tale.
