Prompting with regard to hadd

Narrated AbuUmayyah al-Makhzumi:

A thief who had accepted (having committed theft) was brought to the Prophet ﷺ, but no good were found with him. The Messenger of Allah ﷺ, said to him: I do not think you have stolen. He said: Yes, I have. He repeated it twice or thrice. So he gave orders. His hand was cut off and he was then brought to him. He said: Ask Allah's pardon and turn to Him in repentance. He said: I ask Allah's pardon and turn to Him in repentance. He (the Prophet) then said: O Allah, accept his repentance.

Abu Dawud said: It has been transmitted by 'Amr b. Asim, from Hammam, from Ishaq b. 'Abd Allah from Abu Ummayyah, a man of the Ansar from the Prophet ﷺ.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَبِي الْمُنْذِرِ، مَوْلَى أَبِي ذَرٍّ عَنْ أَبِي أُمَيَّةَ الْمَخْزُومِيِّ، أَنَّ النَّبِيَّ ﷺ أُتِيَ بِلِصٍّ قَدِ اعْتَرَفَ اعْتِرَافًا وَلَمْ يُوجَدْ مَعَهُ مَتَاعٌ فَقَالَ رَسُولُ اللَّهِ ﷺ " مَا إِخَالُكَ سَرَقْتَ " . قَالَ بَلَى . فَأَعَادَ عَلَيْهِ مَرَّتَيْنِ أَوْ ثَلاَثًا فَأَمَرَ بِهِ فَقُطِعَ وَجِيءَ بِهِ فَقَالَ " اسْتَغْفِرِ اللَّهَ وَتُبْ إِلَيْهِ " . فَقَالَ أَسْتَغْفِرُ اللَّهَ وَأَتُوبُ إِلَيْهِ فَقَالَ " اللَّهُمَّ تُبْ عَلَيْهِ " . ثَلاَثًا . قَالَ أَبُو دَاوُدَ رَوَاهُ عَمْرُو بْنُ عَاصِمٍ عَنْ هَمَّامٍ عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ قَالَ عَنْ أَبِي أُمَيَّةَ رَجُلٍ مِنَ الأَنْصَارِ عَنِ النَّبِيِّ ﷺ .
