Sultan Nazrin Shah will lead a special session on Islamic Social Finance at the United Nation’s inaugural World Humanitarian Summit (WHS) in Istanbul. The summit is calling for a 'Grand Bargain' on finance and aid organisations will be told to stop competing for resources. The UN fell short of US$7.5bil (RM30.6bil) in funding needs last year, 30% of what it required. IDB’s research on zakat in 2015 shows an estimated US$600bil (RM2.4 trillion) available to meet humanitarian needs. If 1% of this is made available, it can meet the global funding deficit for 2015.
