Verse 201 of Surah Al-Baqarah, one of the most repeated supplications in Islam.
It asks Allah for good in this world and good in the Hereafter, and for protection from the punishment of the Fire. The Prophet (peace be upon him) often made this dua, and it is recited constantly during Hajj, in prayer, and in everyday supplication for its balance between this life and the next.
- 2:201
وَمِنْهُم مَّن يَقُولُ رَبَّنَآ ءَاتِنَا فِى ٱلدُّنْيَا حَسَنَةًۭ وَفِى ٱلْءَاخِرَةِ حَسَنَةًۭ وَقِنَا عَذَابَ ٱلنَّارِ
Wa minhum mai yaqoolu rabbanaaa aatina fid dunyaa hasanatawn wa fil aakhirati hasanatanw wa qinaa azaaban Naar
Но среди них есть такие, которые говорят: «Господь наш! Одари нас добром в этом мире и добром в Последней жизни и защити нас от мучений в Огне».
