I saw A’bd-u-Qader Gaillani in the sanctuary of the Ka’bah with his face on the pebbles and saying: ‘O lord, pardon my sins and, if I deserve punishment, cause me to arise blind on the day of resurrection that I may not be ashamed in the sight of the righteous.’

With my face on the earth of helplessness
I say Every morning as soon as I become conscious:
O thou whom I shall never forget
Wilt thou at all remember thy slave?
