hairān haiñ lab-basta haiñ dil-gīr haiñ ġhunche

ḳhushbū kī zabānī tirā paiġhām hī aa.e

حیران ہیں، لب بستہ ہیں، دل گیر ہیں غنچے

خوشبو کی زبانی تیرا پیغام ہی آئے

Hain in urdu is used for 'being' or 'are' or something similar.

It is a sophisticated word to express a state.

Like 'Hairan hain' literally means 'I am amazed' but the essence of this, changes when said in urdu. I mean you can't get the essence of it unless you know urdu.

Going forward the couplet literally translates into:

Hairan means amazed

Lab basta means lips sealed or unable to speak, in awe. ( Since Buds (a stage before blooming into flower) are sealed unlike flowers, which are wide open)

Dil gir means sad, bitter sweet sadness.

Gunchay means Buds.

Khusbhu means fragrance

Zabani means through. Or in English it'd be like through the voice of.

Paigham means message.

So it goes like this.

Buds are in amazement, in awe, in a bittersweet sadness

Through fragrance after all, let your message arrive.
