Hadith.1552 - Muhammad ibn Khalid al-Qasri asked Imam Jafar ibn Muhammad Al-Sadiq (as) about seeking divine guidance (istikhara). Imam (as) said: "Seek guidance from Allah (swt) in the last unit (rak'ah) of the night prayer while you are in prostration, repeating it one hundred and one times." Muhammad asked: "How should I say it?" Imam (as) said: "You should say, Astakheeru Allāha bi-raḥmatihi, astakheeru Allāha bi-raḥmatihi. 'I seek guidance from Allah (swt) by His mercy, I seek guidance from Allah (swt) by His mercy.'"
