Immediately after mentioning Hajj in Surah Al-Baqarah, Allah Almighty mentions two major categories of His servants: The first category is those whose sole aim is worldly benefit; regarding them it is stated that such people will have no share in the success of the Hereafter unless they repent and Allah forgives them.
The second category is those whose focus is not only on this world but also on the Hereafter, and their entire life is expressed by this supplicatory phrase:
﴿رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ﴾
"O our Lord! Grant us good in this world and good in the Hereafter, and save us from the punishment of the Hellfire."
Reference: (2-Al-Baqarah:201)
