“The Messenger of Allah supplicated with many supplications of which we did not preserve a thing. We said: ‘O Messenger of Allah, you supplicated with many supplications of which we did not preserve a thing.’ He said: ‘Should I not direct you to what will include all of that? That you say: O Allah, we ask You from the good of what Your Prophet Muhammad asked You for, and we seek refuge in You from the evil of that which Your Prophet Muhammad sought refuge in You from, and You are the one from Whom aid is sought, and it is for You to fulfill, and there is no might or power except by Allah (Allahumma Inna Nasa’luka Min Khairi Ma Sa’alaka Minhu Nabiyyuka Muhammad, Sallallahu Alaihi Wa Sallam, Wa Na’udhu Bika Min Sharri Masta’adha Minhu Nabiyyuka Muhammad, Sallallahu Alaihi Wa Sallam, Wa Antal-Musta’anu Wa Alaikal-Balagh, Wa La Hawla Wa La Quwwata Illa Billah.)’”

“I said to Umm Salamah: ‘O Mother of the Believers! What was the supplication that the Messenger of Allah 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 (Ya Muqallibal-Qulub, Thabbit Qalbi Ala Dinik).’” 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.’”
