Khawaja Badr ud Deen Ghaznawi (Allah have mercy on him) wrote to his pir-bhai,

One of the servants of diwan (treasurer) had built a khanqah for me and arranged for the boarding and lodging of derwishes. Now a charge of embezzlement has been brought against him I am much worried and disturbed. Kindly pray for his release and welfare of the derwishes. 

Baba Fareed ud Deen Masud Ganjshakar (Allah have mercy on him) replied,

‘He who does not follow the principle of his master is confronted with such troubles and worries that his heart gets no peace. Who among our masters did ever construct a khanqah for himself and reside there as you have done. It was not the practice of Shaikh Qutub ud Deen or his master Shaikh Moin ud Deen (Allah have mercy on them) to construct a khanqah and set up a shop. Wherever they went or sojourned, they tried to conceal themselves from the people. ‘
