قَالَ الإِمَامُ الصَّادِقُ عَليهِ السَلامْ:
مَنِ اسْتَخَار اللهَ عَزَّ وَ حَلَّ مَرَّةً وَاحِدَةً وَهُوَ راَضٍ بِمَا صَنَعَ اللهُ لَه خَارَ اللهُ لَهُ حَتْماً.
al‑Imam al‑Sadiq (as) said: "Whosoever asks Allah, the Glorious and the High for the best a single time and is content with what Allah has decided for him, then Allah will definitely make that which is good for him come about. "5
One of the most important etiquette of seeking the best from Allah is that one must have certainty that He will decide the best for His servants and that He has the power to give or withhold whatever is best for His servant.
In short, the servant must have complete satisfaction and peace of heart that after performing the Istikhara, whatever is truly the best for him is the only thing that Allah will decide.
