[Qur'an copied in Bihari script.

Qur'ans in this striking script began to emerge in 14th-century Sultanate India and are characteristically long and narrow in their format, and often have every appearance of 'Allah' copied in a different colour to the main body of text throughout (in the present example Allah is copies in red). They are also distinctive for the use of this stylised bihari script which characteristically has emphasis in the sub linear elements of the letters which are greatly thickened and end in sharp points. The script is believed to be derived from naskh script during the Sultanate period, which began it's demise and fall to the Mughal Empire in the early sixteenth century and unlike other specialised regional scripts, like the maghribi script of North Africa that has survived until the present day, this bihari script had virtually disappeared in India by the late sixteenth century. The present example is one rare that appeared after the fall of Sultanate India and before the scribal practices associated with this style had dissolved in the region.
