“I said to Umm Salamah: ‘O Mother of the Believers! What was the supplication that the Messenger of Allah (ﷺ) said most frequently when he was with you?” She said: ‘The supplication he said most frequently was: “O Changer of the hearts, make my heart firm upon Your religion (Yā Muqallibal-qulūb, thabbit qalbī `alā dīnik).’” She said: ‘So I said: “O Messenger of Allah, why do you supplicate so frequently: ‘O Changer of the hearts, make my heart firm upon Your religion.’ He said: ‘O Umm Salamah! Verily, there is no human being except that his heart is between Two Fingers of the Fingers of Allah, so whomsoever He wills He makes steadfast, and whomever He wills He causes to deviate.’”
Allaahumma innee as-aluka ath-Thabata fil Amr, wal azeemata alar-Rushd, wa as-aluka Moojibati Rahmatika wa Azaaima Maghfiratika, wa as-aluka Shukra Ni’matik, wa husna ibadaatik, wa as-aluka Qalban Saleeema wa Lisaanan Saadiqa, wa as-Aluka min khairi ma Ta’lamu, wa Audhubika min Sharri ma Ta’lamu, wa astaghfiruka limaa Ta’lamu, Innaka Anta Allaamul- Ghuyoob.
O Allaah verily I ask of You for strength of perseverance of obedience on the Deen, and determination in practicing of the Deen and goodness. And I ask of You for that which obligates Your mercy and resolutions for Your forgiveness. And I ask of You for the capability to be thankful for Your blessings and to worship you in a correct and good way. And I ask of You for a heart which is purified in belief and free from desires and a truthful tongue. And ask of You for the best of what You know, and I seek refuge with You from the evil of what You know and I seek forgiveness for that which You know. Indeed You are the One who knows the unseen.
