"`This name comes to them,' said Haji Karim Khan in his Hidayatu't-Talibin, `from the fact that the late Shaykh Ahmad, being at Karbila during his pilgrimages to the holy tombs, and out of respect for the Imams, recited his prayers standing behind the Imam, that is to say, at his feet. In fact, for him there was no difference between the respect to be tendered to a dead Imam or a living Imam. The Persians, on the contrary, when entering into the tomb, placed themselves at the head of the Imam and consequently turned their backs to him when they prayed because the dead saints are buried with their heads towards the Qiblih. This is a disgrace and a lie! The apostles of Jesus pretending to have come to the assistance of God, were called ` Nasara,' a name which was given to all those who followed in their footsteps. It is thus that the name of Bala-Sari extended to all that follow the doctrine of those who pray standing at the head of the Imam.'" (A. L. M. Nicolas' "Essai sur le Shaykhisme," I, preface, pp. 5-6.)
