“Rabbighfir li, Rabbighfir li (O Lord forgive me, O Lord forgive me).”  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقُولُ بَيْنَ السَّجْدَتَيْنِ رَبِّ اغْفِرْ لِي رَبِّ اغْفِرْ لِي  

“When praying at night (Qiyamul-Lail), the Messenger of Allah ﷺ used to say between the two prostrations: ‘Rabbighfir li warhamni wajburni warzuqni warfa’ni (O Lord, forgive me, have mercy on me, improve my situation, grant me provision and raise me in status).’”  

كَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ بَيْنَ السَّجْدَتَيْنِ فِي صَلاَةِ اللَّيْلِ رَبِّ اغْفِرْ لِي وَارْحَمْنِي وَاجْبُرْنِي وَارْزُقْنِي وَارْفَعْنِي
