Learn as many supplicatons / duas as possible

I have the book “Hisnul Muslim”.

I read duas for every occasion especially when I need to make a life changing decision or worried and before I knew I memorized many of those duas. My favorite dua is dua Al Istikhara. If anyone asks me an advice I tell them to pray two rakat and read dua al istikharah and Allah guides them to the right decision.

Dua Al Istikhara

WAY TO PERFORM ISTIKHARA:
First pray two cycles of ritual prayer [raka’] such that in the first raka’ after Surah Fatiha (Allhamd…) recite Surah al-Kafirun (Chapter 109) and in the second raka’ after Fatiha (Allhamd…) recite Surah al-Ikhlas (Chapter 112) and after finishing prayer [salam] then recite this (supplication/dua’): Dua in Arabic Text above.

TRANSLATION: “O Allah! I seek goodness from Your Knowledge and with Your Power (and Might) I seek strength, and I ask from You Your Great Blessings, because You have the Power and I do not have the power. You Know everything and I do not know, and You have knowledge of the unseen. Oh Allah! If in Your Knowledge this action —-—-—-—-—-—-—-—-—-- (which I intend to do) is better for my religion and faith, for my life and end [death], for here [in this world] and the hereafter then make it destined for me and make it easy for me and then add blessings [baraka’] in it, for me. O Allah! In Your Knowledge if this action is bad for me, bad for my religion and faith, for my life and end [death], for here [in this world] and the hereafter then turn it away from me and turn me away from it and whatever is better for me, ordain [destine] that for me and then make me satisfied with it.”
