One day in Delhi the renowned Sufi saint, Nizamuddin Aulia ( 1238-1325 ), was standing with his disciple Amir Khusro ( 1253-1325 ), on the bank of the river Jumna.
The saint saw Hindu worshippers bathing in the Jumna, and remarked (in Persian) :
“Har Qaum raast raahe
Din-e-wa qibla gaahe”
“Every people has a pole (qibla) to which it turns”
i.e.: Every sect has its own right path of worship.
Amir Khusro immediately completed the couplet with a verse of his own:
“Man qibla raast kardam
bar samt kaj kulahe”
“I, however turn my face
towards the tilted cap”
In other words, Amir Khusro said that his path was that of Nizamuddin Aulia, i.e. Sufiism
(Nizamuddin Aulia used to wear a tilted cap).
