On the 17th Ramadan the Battle of Badr is commemorated, which took place on that day in the second year of the Hijrah.
It is one of the most important events in the history of the Ummah, and Allah describes it as the Day of Discrimination (between truth and falsehood).
Donate £100 on behalf of one, £200 on behalf two, £300 on behalf of three, or £400 on behalf of four of the blessed 313 companions who fought in this battle.
