Assalam O Aliakum
The Messenger of Allah (s.a.w.s.) said:
If your sustenance reduces and you have difficulties in your affairs you must remove them by asking your needs from the Almighty with the help of Namaz and Isteghfar. Namaz-e-Isteghfar is two rakats. In each rakat after Surah Hamd recite Surah Qadr once and then say Astaghfirullaah 15 times. Then go into the ruku and after the recitation of the ruku say Astaghfirullaah 10 times. Rise up from the ruku and again say it 10 times. Go into the first Sajdah and after the recitation of the Sajdah say Astaghfirullaah 10 times. Arise from the first Sajdah and again say Astaghfirullaah 10 times. Go into the second Sajdah and repeat like the first Sajdah. Get up from the second Sajdah and say Astaghfirullaah 10 times. In the similar manner complete the second rakat and conclude the prayer. Insha Allah everything would be all right.
Recite “Astaghfirullaah Rabbee Wa Atoobu Ilayh” as many times as possible in Shab e Baraat, with sincerity.
