the Prophet (saas) used to say: "Allahumma inni as'alukal-huda wat-tuqa wal-'afaf wal-ghina (O Allah, I ask You for guidance, piety, chastity and affluence)." (Using translation from Ibn Mājah 3832)
أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ اللهُمَّ إِنِّي أَسْأَلُكَ الْهُدَى وَالتُّقَى وَالْعِفَّةَ وَالْغِنَى
