The Quraysh sent me to the Messenger of Allah ﷺ, and when I saw the Messenger of Allah ﷺ, Islam was cast into my heart, so I said: Messenger of Allah, I swear by Allah, I shall never return to them. The Messenger of Allah ﷺ replied: I do not break a covenant or imprison messengers, but return, and if you feel the same as you do just now, come back. So I went away, and then came to the Prophet ﷺ and accepted Islam. The narrator Bukair said: He informed me that Abu Rafi' was a Copt. Abu Dawud said: This was valid in those days, but today it is not valid. (Using translation from Abū Dāʾūd 2758)   

أَخْبَرَهُ أَنَّهُ أَقْبَلَ بِكِتَابٍ مِنْ قُرَيْشٍ إِلَى رَسُولِ اللهِ ﷺ فَلَمَّا رَأَيْتُ النَّبِيَّ ﷺ أُلْقِيَ فِي قَلْبِي الْإِسْلَامَ قُلْتُ يَا رَسُولَ اللهِ «إِنِّي وَاللهِ لَا أَرْجِعُ إِلَيْهِمْ أَبَدًا» قَالَ رَسُولُ اللهِ ﷺ إِنِّي لَا أَخِيسُ بِالْعَهْدِ وَلَا أَحْبِسُ الْبَرْدَ وَلَكِنِ ارْجِعْ فَإِنْ كَانَ فِي قَلْبِكَ الَّذِي فِي قَلْبِكَ الْآنَ فَارْجِعْ فَرَجَعْتُ إِلَيْهِمْ ثُمَّ أَقْبَلْتُ إِلَى رَسُولِ اللهِ ﷺ فَأَسْلَمْتُ قَالَ بُكَيْرٌ «وَأَخْبَرَنِي أَنَّ أَبَا رَافِعٍ كَانَ قِبْطِيًّا»
