In wanting to serve refugees and families in need during winter, have you thought to call clothing and blankets stores, as well as major factories and warehouses, to urge them to help provide winter clothing to those who need it most? They may have what you can collect to donate and distribute to those in need, thereby helping warm their bodies, as well as their hearts.
Allah (sublime be He) says: {So fear Allah as much as ye can; listen and obey and spend in charity for the benefit of your own soul and those saved from the covetousness of their own souls,- they are the ones that achieve prosperity. * If ye loan to Allah, a beautiful loan, He will double it to your (credit), and He will grant you Forgiveness: for Allah is most Ready to appreciate (service), Most Forbearing}. (Surat at-Taghabun, verse 16-17).
