The Prophet ﷺ said, “There is no supplication that a person can say that is better than:

‘O Allaah! I ask You for al-Mu’aafaah* in this world and the Hereafter.’” *(‘Mu’aafaah is for Allaah to suffice you against needing the people, and sufficing the people of having need of you. See Tuhfatul-Ahwadhi, 3512.)

Allaahumma inni as’alukal-Mu’aafaah fid-Dunyaa wal-Aakhirah

اَللَّهُمَّ إِنِّيْ أَسْأَلُكَ الْمُعَافَاةَ فِيْ الْدُّنْيَا وَالْآخِرَةِ
