The night he would not stop asking
Abū Bakr eventually took hold of his hand and told him it was enough.
اللَّهُمَّ إِنِّي أَنْشُدُكَ عَهْدَكَ وَوَعْدَكَ، اللَّهُمَّ إِنْ تَشَأْ لاَ تُعْبَدْ بَعْدَ الْيَوْمِ
Allāhumma innī anshuduka ʿahdaka wa waʿdak.
“O Allah, I appeal to You by Your covenant and Your promise.”
He kept asking until his cloak fell from his shoulders and Abū Bakr put it back on him.
The full narration
Narrated Ibn `Abbas:Allah's Messenger (ﷺ) while in a tent on the day of the Battle of Badr, said, "O Allah! I request you (to fulfill) Your promise and contract! O Allah! If You wish that you will not be worshipped henceforth.." On that Abu Bakr held the Prophet (ﷺ) by the hand and said, "That is enough, O Allah's Messenger (ﷺ) You have appealed to your Lord too pressingly," while the Prophet (ﷺ) was putting on his armor. So Allah's Messenger (ﷺ) went out, reciting Their multitude will be put to flight, and they will show their backs
