Ибн Баттута
Ibn Battuta, the Moroccan Muslim traveller, left extensive notes on Tughlaq dynasty in his travel memoirs. Ibn Battuta arrived in India through the mountains of Afghanistan, in 1334, at the height of Tughlaq dynasty's geographic empire. On his way, he learnt that Sultan Muhammad Tughluq liked gifts from his visitors, and gave to his visitors gifts of far greater value in return. Ibn Battuta met Muhammad bin Tughluq, presenting him with gifts of arrows, camels, thirty horses, slaves and other goods. Muhammad bin Tughlaq responded by giving Ibn Battuta with a welcoming gift of 2,000 silver dinars, a furnished house and the job of a judge with an annual salary of 5,000 silver dinars that Ibn Battuta had the right to keep by collecting taxes from two and a half Hindu villages near Delhi.
