Sunan Ibn Majah Book 5, Hadith 95
“Rabbighfir li, Rabbighfir li (O Lord
forgive
me, O Lord forgive me).”
“The Prophet (ﷺ) said to me: ‘When you raise your head from prostration, do not squat like a dog. Put your buttocks between your feet and let the tops of your feet touch the ground.”
“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).’”
