Will Allah hold one accountable for a supplication made against oneself in a moment of anger between the Adhan and the Iqamah?

Since you have repented and sought forgiveness, you bear no blame. Replace your supplication against yourself with a supplication for good for yourself, and trust in the generosity and mercy of Allah, for by His grace, He does not answer every evil thing a person prays for, as He states: "And if Allah were to hasten for the people the evil [they invoke] as He hastens the good, their term would have been ended for them" (Yunus: 11). So, by His forbearance, Allah does not answer when they pray against themselves, their wealth, or their children in states of distress and anger, unlike their prayers for good, blessings, and growth.
