The supplication that never left the tongue of Rasûlullah (PBUH), protecting the heart…
Hazrat Anes -may Allah be pleased with him- narrates:
The Supplication Our Prophet (PBUH) Frequently Recited: Steadfast My Heart Upon Your Religion!
Rasûlullâh -peace and blessings of Allah be upon him- frequently recited the following supplication:
َ يَا مُقَلِّبَ القُلُوبِ ثَبِّتْ قَلْبِي عَلٰى دِينِكَ
“O Allâh, Turner of hearts, make my heart steadfast upon your religion!”
I (once) said to him:
“–O Messenger of Allah! We believe in You and that which you have brought. Are you fearful for us?” He replied to me as follows:
“Yes! Hearts are between the two fingers of the Most Merciful. He turns them as He wills.” (Tirmidhi, Qadar, 7/2140)
