Retrieving your right

If a person is being owed some money or some other right. But the debtor is delaying for no justified reason.

Then he should recite  يا مُذِلّ alot. InshaAllah, he will receive his right very quickly.

One may also read 2 Rakaats of Salaatul Haajah, and recite this 75 times in Sajdah.

Thereafter turn to Allah in dua.
