ثَنَا شَيْبَانُ عَنْ قَتَادَةَ قَالَ وَجَدْتُ مَرْثَدَ بْنَ ظَبْيَانَ قَالَ جَاءَنَا كِتَابٌ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَمَا وَجَدْنَا لَهُ كَاتِبًا يَقْرَؤُهُ عَلَيْنَا حَتَّى قَرَأَهُ رَجُلٌ مِنْ بَنِي ضُبَيْعَةَ ”مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِلَى بَكْرِ بْنِ وَائِلٍ أَسْلِمُوا تَسْلَمُوا“
Qatadah narrates: He says, I met Mirthad bin Zubyan, who said: A letter from the Messenger of Allah, peace and blessings be upon him, came to us, and we could not find anyone who could read it out to us. Eventually, a man from Banu Zubay‘ah read the letter, and it contained the following: From the Messenger of Allah, peace and blessings be upon him, to Abu Bakr bin Wa’il: Accept Islam, you will be safe.
