(Surah Bani Israel/Al-Isra (17), Verse 80)

رَّبِّ أَدْخِلْنِى مُدْخَلَ صِدْقٍ وَأَخْرِجْنِى مُخْرَجَ صِدْقٍ وَٱجْعَل لِّى مِن لَّدُنكَ سُلْطَـٰنًا نَّصِيرًا

Rabbi adkhilnee mudkhala sidqinw wa akhrijnee mukhraja sidqinw waj'al lee milladunka sultaanan naseeraa.

My Lord! ‘Admit me with a worthy entrance, and bring me out with a worthy departure, and render me a favourable authority from Yourself.

(Surah Bani Israel/Al-Isra (17), Verse 80)

Here, the term "Sultaanan Naseera" is used. It refers to a powerful supporter (helper) who never hesitates to help - one who is strong and provides continuous assistance.
This prayer is from my personal experience. Whenever I faced any kind of difficulty, I repeatedly recited this supplication during Namaz e Shab (Tahajjud). This is a proven practice. The condition is that along with this prayer, one must also follow Allah's commands. In your own life and within your family—wherever you have authority—you must act with honesty and justice. Then observe the impact of this prayer. I have specifically shared this prayer with some friends in distress, and their difficulties were resolved as well.
