The whole ghazal is about wanting things to start moving again, written by somebody who cannot move. That is where the ache comes from. Every image in it travels: a breeze goes, a morning breaks, people come walking, tears run, a man walks to the gallows. And the person asking for all of it is sitting still in a cell.
The second couplet is the only one that says where he is. The cage is low today, friends. Somebody have a word with the morning breeze. Let there at least be some mention of the beloved. After a lifetime of asking for large things, this is the request that remains: that her name come up somewhere, in somebody's mouth, today. Bahr-e-khuda, for God's sake, is what you say once you have stopped being reasonable.
Then comes one of the strangest things Faiz ever wrote. Speaking to the night of separation itself, he says: what happened to us happened, but our tears have gone and made your afterlife respectable. Aaqibat is a strictly religious word, your standing on the day of judgement. He is telling the night that it will be saved on the strength of the suffering it caused him, and there is not a drop of anger in the telling.
With that in the room, the opening couplet is no longer an ordinary spring poem. It asks for the garden's karobar to resume, which is a commercial word: trade, the running of a concern. In Faiz's poetry the garden is usually the country. So the first thing this poem asks for is that the whole enterprise start working again, phrased as a remark about the weather, by a man the state had locked up.
And then it refuses an ordinary ending. Not one stopping-place along the road ever looked good enough, so whoever leaves the beloved's street walks straight on to the gallows. Ku-e-yar and su-e-daar are barely a sound apart in Urdu, and the beloved's street and the gallows turn out to be the same street. Mehdi Hassan's is the recording most people meet it in, and the reason a lot of listeners know Faiz at all.
How it rhymes
Every second line closes on the same word — چلے
, chale. That repetition is the radif.
The rhyme falling just before it is the qafiya: The -aar sound just before the refrain: nau-bahar, karobar, zikr-e-yar, mushk-bar, gham-gusar, sanvar, taar taar, su-e-daar.
Hearing the two land together at the close of every sher is most of what makes this form sound the
way it does.
