It was narrated from 'Ā'ishah -raḍhiyallāhu ‘anhā- that she said:

"O Messenger of Allāh, what should I say in my supplication if I reach Laylatul-Qadr?" He said: "Say: 'Allāhumma innaka 'afuwwun tuḥibbul-'afwa, fa'fu 'anni (O Allāh, You are Forgiving and love to forgive, so forgive me).'" Reported by Tirmithī (8025) | graded "Ṣaḥīḥ" by Sheikh Albāni in Silsilah Aṣ-Ṣaḥīḥah __ There must be a reason why the Prophet ﷺ specified this du'ā, so let us reflect over these concise words... The word ‘Afw (pardon/wellbeing) entails: 1⃣ - wellbeing in one's limbs 2⃣ - wellbeing in one's religion 3⃣ - pardon and forgiveness from Allāh Wellbeing in one's limbs is cure and safety from all types of illness. Wellbeing in one's religion is being granted success to perform righteous deeds. Pardon & forgiveness from Allāh is that He overlooks and pardons one's sins by erasing them and not punishing him for them. Additionally, from the linguistic meanings of "Al 'Afw" is: increment and abundance. For example, ‘Afw in wealth refers to it’s increment, as Allāh ﷻ said: {یَسۡـَٔلُونَكَ مَاذَا یُنفِقُونَۖ قُلِ ٱلۡعَفۡوَ} “They ask you [O Mūḥammad ﷺ] what they should spend, Say, Al 'Afw” [Sūrah Al-Baqarah 219] i.e. that which is surplus to one's necessary expenditure. And Allāh's ‘Afw is that He grants a person what he asks for AND MORE. So let us increase in repeating this du'ā without slackening - especially during these blessed nights. ((اللَّهُمَّ إِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي)) “O Allāh, You are the One Who pardons and loves to pardon, so pardon us.” Ref: https://t.me/ShaykhYahyaEn/716
