Asking Allah for 'Aafiyah
Abu Bakr once stood up on the minbar (pulpit) and cried. He then said that Nabi (ﷺ) also stood on the minbar the first year after hijrah, cried and said:
اسألوا الله العفو والعافية، فإن أحدا لم يعط بعد اليقين خيرا من العافية
Ask Allah for 'Afw (Pardon/forgiveness) and ‘Aafiyah (Protection/wellbeing) for verily after yaqeen, none is given anything better than ‘Aafiyah.
[Tirmidhi]
Ibn Umar reported: The Messenger of Allah (ﷺ) said:
ما سئل الله شيئا أحب إليه من أن يسأل العافية
Allah is not asked for anything more beloved to him than [being asked about] 'Aafiyah.
[Tirmidhi]
Anas bin Malik reported: The Prophet (ﷺ) said:
فإذا أعطيت العافية في الدنيا وأعطيتها في الآخرة فقد أفلحت
If you are given 'Aafiyah in this world and the next then you have succeeded.
[Tirmidhi]
Ibn Qutaybah said:
The word 'Aafiyah means safety from the evils of this world and the horrors of the Hereafter.
[Gharib al Hadith]
A simple way you can repeat:
اللَّهُمَّ إِنِّي أَسْأَلُكَ الْعَفْوَ وَالْعَافِيَةَ فِي الدُّنْيَا وَالْآخِرَةِ، رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ
Allahumma inni asalukal ‘afwa wal ‘āfiyah fid dunyā wal ākhirah. Rabbanā ātinā fid dunyā hasanah wa fil ākhirati hasanah wa qinā ‘adhāban nār.
O Allah , I ask You for 'Afw (Pardon/Forgiveness) and 'Aafiyah in this world and the hereafter. Our Lord, give us that which is good in this world and that which is good in the Hereafter, and protect us from the torment of the Fire
