Find the radif first: it is the identical tail of both lines of the matla. Then the word just before it is the qafia. The qafia words must share their final vowel and everything after it (the harf-e-ravi and what follows).
Radif: hone tak. Qafia: asar / sar, and later in the ghazal khabar. The shared sound is -ar.
Radif: jaa'eñ ge. Qafia: mar / kidhar.
