A rule in Urdu Poetry states that, in the form of poetry known as a Ghazal the second line of all the Shers must end with the same word/s. This repeating common words is the 'Radif' of the Ghazal. It is proceeded by a by a Qaafiyaa, which is a repeating pattern of words.

The following is an example of a Ghazal by Daag Dehelvi

In this example the Radif is mein.

The Kaafiyaa is the following pattern of words: jalwa-gaah, nigaah, raah, haale-tabaah and aah
