The month of Ramadan is not about starving the stomach, it is about starving yourself from the dunya and from that which moves you further away from Allah. 

Ramadan is about ibadah, to rebuild and/or strengthen your relationship with Allah. One of which way to do so is through giving charity. 

I have pledged to raise money for Baitul Aman to help the construction of the mosque. Please donate kindly. 

When giving charity, give wholeheartedly with pure intentions and you shall receive the blessing of Allah in abundance in return  ان شاء الله.
