For 7 days after Esha Salah do 2 Rakat nafal. In every sajde read 40 times ayet karima (la ilaha illa anta subhanaka inni kunto minaz zalimeen.). Do not read anything else in the sajde. After you finish the nafal do a dua and ask for your hajat. As usual Darood/Salwat 11 times before and after the dua.

What ever you wish will happen within 7 days. This is guaranteed by the Prophet (sallal laho alihey wa alehi wa sallaim) himself. This wazifa was told to a Wali Allah by the Prophet (sallal laho alihey wa alehi wa sallaim).

It has never ever failed to get the reader what he wants. You can hold a tasbeeh in your hand during a sajde to count.
