Explanation:

The first known mention of the word ‘Punjab’ is in the writings of ibneBatuta, who visited this most fertile region in the 14th century. However, in the great epic of Mahabharata, the Sanskrit equivalent of Punjab is narrated as Pancha-nada (country of five rivers). The name Punjab is again mentioned in Aine-e-Akbari(Part-I), written by AbulFazal. The Mughal King Jahangir also mentions the word Punjab in Tuzk-i-Jahangiri. Punjab in Persian literally means ‘Panj’ (five) and ‘ab’ (waters) i.e. the land of five rivers, referring to the five rivers which run through it.
