Majaz here means material form (visible form). Iqbal is saying
Allah show me urself in a visible form so that i offer thousands
prostrations to you. Iqbal is the poet who have many poems in which
he talks as two persons like shikwa jawab-e-shikwa, he himself
first complaint to God and then writes reply by God and negates his
complaint in 'shikwa'.If you read whole poem u will see in first
verse saysAllah show me yourself in visible form and then after
that in many verses he is saying that love has lost purity and
madness why a lover should need the proof of existence of beloved
if he truly loves him. The last verse is the reply in itself of
your question. Try to read the first and last verses together.Kabhi
Ae Haqiqat-e-Mutazir! Nazar Aa Libas-e-Majaz MeinKe Hazar Sajde
Tarap Rahe Hain Meri Jabeen-e-Niaz MeinJo Mein Sar Basajda Huwa
Kabhi To Zameen Se Ane Lagi SadaTera Dil To Hai Sanam Ashna, Tujhe
Kya Mile Ga Namaz MeinO awaited reality for once show urself in
material (visible) form as thousands of prostrations are quivering
in my submissive forehead and (the reply to negate his own words)
when i laid down my head for prostration i heard a voice from earth
'your heart is in materialism' no rewards for your prayers are.
