One of the procedures for fulfillment of big requests is to do ritual ablution (Ghusl) on the Thursday night (the night before Friday). There is no need for Ghusl at the next nights. Then, at the first night (which is the night before Friday), and the other nights, you shall recite for thousand times followings:

Thursday night:

اللهم صل علي محمد و آل محمد. (Allahumma Salle Ala Mohammad va Aale Mohammad)

Friday night:

اللهم صل علي اميرالمؤمنين. (Allahumma Salle Ala Ali Amiralmomenin)

Saturday night:

اللهم صلّ علي فاطمة. (Allahumma Salle Ala Fatimah)

Sunday night:

اللهم صلّ علي الحسن. (Allahumma Salle Alal Hassan)

Monday night:

اللهم صلّ علي الحسين. (Allahumma Salle Alal Hossein)

The whole procedure takes two weeks.

Fifth procedure:

The method of Tawassol to Hazrat Qamar Bani Hashem (a.s.):

On Tuesday night, pray two Rakat, and after the prayer, repeat 133 times:

يا كاشف الكرب عن وجه الحسين عليه السلام

(Ya Kashefal Karb An Vajhel Hossein Alayhessalam)

اكشف كربي بحق اخيك الحسين عليه السلام

(Ekshef Karbi Be Haqqe Akhikal Hossein Alayhessalam)

And repeat one hundred times for seven Tuesday nights:

O Moon of Bani Hashem, the sun of meeting, Abbas,

O Light of heart of Heydar (Ali), the candle of martyrs

We have resorted to Thee due to grief, pain, and sorrow

For God's sake, help me that I am helpless, O Abbas

It has been narrated from the Grand Ayatollah, Haj Sayed Mahmoud Hosseinin Shahroudi (May his spirit be sanctified) that when facing with a problem, I recited one hundred times Salavat (Allahomma Sallle Ala Mohammad va Ale Mohammad) for the mother of Hazrat Abalfazl Abbas (a.s.), Ommolbanin.

Four Thursday nights, ten times you shall recite Ya Sin sura as follows:

First Thursday night: three times
Second Thursday night: three times
Third Thursday night: three times
Fourth Thursday night: one time Ya Sin sura on behalf of Hazrat Abalfazl Abbas (a.s.) and presenting to his mother (Ommolbanin). The request would be fulfilled Inshallah.
