The tomb of the famous sufi saint Nizam-ud-din Auliya is built on the way from Humayun’s tomb. Inside the premises of the shrine is a tank which is surrounded by many other tombs. It is said that there was a controversy between the rulers of Tughlakabad and the saint over building this tank. The saint had said that the city of Tughlakabad will never flourish and so did it happen. The shrine also has the tomb of Amir Khusru and the grave of Jahanara, the daughter of Shah Jahan. It is worth visiting the shrine at around sunset on Thursdays, as it is a popular time for worship, and qawwali singers start performing after the evening prayers.
