Famous quotes containing the word glass:

    “Thou didst create the night, but I made the lamp.
    Thou didst create clay, but I made the cup.
    Thou didst create the deserts, mountains and forests,
    I produced the orchards, gardens and groves.
    It is I who made the glass out of stone,
    And it is I who turn a poison into an antidote.”
    —Muhammad, Sir Iqbal (1873–1938)
