Every year we are doing Qurbani but this year we could not buy the Goat as in market it was not worth of that price they were asking

this condition occurred on the last day as my house in under renovation
so kindly guide that still i have to do it or not

No doubt Qurbani is wajib fir the someone who is doing Haj for other people it is highly recommended, still not wajib but if one is unable to do the Qurbani then off course it will not applied.
