A newbie's question

Hi

I have just joined and I look forward to an interesting time here.

I'm not a big fan of Shayari but am an admirer of the beauty of arrangement of words (which shayari is all about). I might sound as if I'm contradicting myself here but this is true.

This question might be coming too soon, but I came across these lines

Koi toh hansi ki baat nikle
Chahe zikr-e-qayamat hi ho

Can anybody help me with the source and the context, please?
