"A man come to the Prophet (saas) and said: 'O Messenger of Allah, what supplication is best?' He said: 'Ask your Lord for forgiveness and to be kept safe and sound in this world and in the Hereafter.' Then (the man) came the next day and said: 'O Messenger of Allah, what supplication is best?' He said: 'Ask your Lord for forgiveness and to be kept safe and sound in this world and in the Hereafter.' Then (the man) came the third day and said: 'O Prophet of Allah, what supplication is best?' He said: 'Ask your Lord for forgiveness and to be kept safe and sound in this world and in the Hereafter, for if you are forgiven and kept safe and sound in this world and the Hereafter, you will have succeeded.'"  

أَتَى النَّبِيَّ ﷺ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ أَىُّ الدُّعَاءِ أَفْضَلُ قَالَ سَلْ رَبَّكَ الْعَفْوَ وَالْعَافِيَةَ فِي الدُّنْيَا وَالآخِرَةِ ثُمَّ أَتَاهُ فِي الْيَوْمِ الثَّانِي فَقَالَ يَا رَسُولَ اللَّهِ أَىُّ الدُّعَاءِ أَفْضَلُ قَالَ سَلْ رَبَّكَ الْعَفْوَ وَالْعَافِيَةَ فِي الدُّنْيَا وَالآخِرَةِ ثُمَّ أَتَاهُ فِي الْيَوْمِ الثَّالِثِ فَقَالَ يَا نَبِيَّ اللَّهِ أَىُّ الدُّعَاءِ أَفْضَلُ قَالَ سَلْ رَبَّكَ الْعَفْوَ وَالَعَافِيَةَ فِي الدُّنْيَا وَالآخِرَةِ فَإِذَا أُعْطِيتَ الْعَفْوَ وَالْعَافِيَةَ فِي الدُّنْيَا وَالآخِرَةِ فَقَدْ أَفْلَحْتَ  

he heard Abu Bakr, when the Prophet (saas) had passed away, saying: "The Messenger of Allah (saas) stood in this place where I am standing, last year." Then Abu Bakr wept, then he said: "You must adhere to the truth, for with it comes righteousness and they both lead to Paradise. And you must beware of lying for with it comes immorality, and they both lead to Hell. Ask Allah for Al-Mu'afah, for no one is given anything after certainty that is better than Mu'afah. Do not envy one another, do not hate one another, do not sever ties with one another, do not turn your backs on one another and be, O slaves of Allah, brothers."  

أَنَّهُ سَمِعَ أَبَا بَكْرٍ حِينَ قُبِضَ النَّبِيُّ ﷺ يَقُولُ قَامَ رَسُولُ اللَّهِ ﷺ فِي مَقَامِي هَذَا عَامَ الأَوَّلِ ثُمَّ بَكَى أَبُو بَكْرٍ ثُمَّ قَالَ عَلَيْكُمْ بِالصِّدْقِ فَإِنَّهُ مَعَ الْبِرِّ وَهُمَا فِي الْجَنَّةِ وَإِيَّاكُمْ وَالْكَذِبَ فَإِنَّهُ مَعَ الْفُجُورِ وَهُمَا فِي النَّارِ وَسَلُوا اللَّهَ الْمُعَافَاةَ فَإِنَّهُ لَمْ يُؤْتَ أَحَدٌ بَعْدَ الْيَقِينِ خَيْرًا مِنَ الْمُعَافَاةِ وَلاَ تَحَاسَدُوا وَلاَ تَبَاغَضُوا وَلاَ تَقَاطَعُوا وَلاَ تَدَابَرُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا  

"O Messenger of Allah, what do you think I should say in my supplication, if I come upon Laylatul-Qadr?" He said: "Say: 'Allahumma innaka 'afuwwun tuhibbul-'afwa, fa'fu 'anni (O Allah, You are Forgiving and love forgiveness, so forgive me).'"  

أَنَّهَا قَالَتْ يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِنْ وَافَقْتُ لَيْلَةَ الْقَدْرِ مَا أَدْعُو قَالَ تَقُولِينَ اللَّهُمَّ إِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي  

"The Messenger of Allah (saas) said: 'There is no supplication that a person can say that is better than: Allahumma inni as'aluka al-mu'afah fid-dunya wal-akhirah (O Allah, I ask You for Al-Mu'afah in this world and in the Hereafter).'"  

قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ دَعْوَةٍ يَدْعُو بِهَا الْعَبْدُ أَفْضَلَ مِنَ اللَّهُمَّ إِنِّي أَسْأَلُكَ الْمُعَافَاةَ فِي الدُّنْيَا وَالآخِرَةِ
