Steadfastness on Deen
Hadhrat Shuhra Bin Jausab (RA) says, “I asked Umm-e-Salma (RA), ‘What was Rasulullah (Sallallahu Alayhi Wassallam)’s most often read/repeated du’a in his house?’” She replied that Rasulullah (Sallallahu Alayhi Wasallam) used to read:
يا مقلب القلوب ثبت قلبي علي دينك
Transliteration: “Ya muqallibal quloob thabbit qalbi ‘ala deenik.”
Translation: “Oh Controller of hearts! Make my heart firm on Your Deen.”
(Jawaahir ul Bukhari, pg. 571)
One who continuously makes this du’a will remain steadfast on the Deen, with the result that he will die with Imaan.
