مروي عن الأئمة المعصومين عليهم السلام في كتب الأدعية المعتبرة.
This supplication, known as Dua e Hifz e Imaan (Prayer for the Preservation of Faith), was taught by Imam Ja'far al-Sadiq (a.s.). Muhammad ibn Sulayman al-Daylami narrated that he asked the Imam to teach him a supplication to perfect and preserve his faith. The Imam instructed him to recite this prayer after each obligatory prayer. There is a scholarly discussion regarding Dua al-'Adilah, with some scholars, like Hajj Mirza Husayn al-Nuri, stating it was composed by scholars and not found in famous Hadith books. The prayer presented here is specifically the one taught by Imam Sadiq (a.s.) for strengthening faith.
Dua hii, inayojulikana kama Dua ya Hifdhul Imani (Dua ya Kuhifadhi Imani), ilifundishwa na Imam Ja'far al-Sadiq (a.s.). Muhammad ibn Sulayman al-Daylami alisimulia kwamba alimuuliza Imam amfundishe dua itakayokamilisha na kuhifadhi imani yake. Imam alimuelekeza kuisoma dua hii baada ya kila sala ya faradhi. Kuna majadiliano ya kielimu kuhusu Dua al-'Adilah, ambapo baadhi ya wanazuoni, kama Hajj Mirza Husayn al-Nuri, wanasema iliandikwa na wanazuoni na haipatikani katika vitabu maarufu vya Hadith. Dua inayowasilishwa hapa ndiyo hasa iliyofundishwa na Imam Sadiq (a.s.) kwa ajili ya kuimarisha imani.
