The following is a zikr khafi, or that which is performed in either a low voice or mentally.

Closing his eyes and lips, he says, "with the tongue of the heart,"

Allahu Sami'un, "God the Hearer."

Allahu Basirun, "God the Seer."

Allahu 'Alimun, "God the Knower."

The first being drawn, as it were, from the navel to the brain; the second, from the breast to the brain; the third, from the brain up to the heavens; and then again repeated stage by stage backwards and forwards.

He says in a low voice, "Allah," from the right knee, and then from the left side.

With each exhalation of his breath, he says, "la ilaha," and with each inhalation, "illa 'llahu."

This third zarb is a most exhausting act of devotion, performed, as it is, hundreds or even thousands of times, and is therefore considered the most meritorious.

It is related that Maulawi Habibu 'llah, living in the village of Gabasanri, in the Gadun country, on the Peshawur frontier, became such an adept in the performance of this zarb, that he recited the first part of the zikr 'la ilaha' with the exhalation of his breath after the mid-day prayer; and the second part, 'illa 'llahu,' with the inhalation of his breath before the next time of prayer, thus sustaining his breath for the period of about three hours!
