حَدَّثَنَا رَوْحُ بْنُ عَبْدِ الْمُؤْمِنِ، قَالَ‏:‏ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ قَالَ‏:‏ رَأَيْتُ رَسَائِلَ مِنْ رَسَائِلِ النَّبِيِّ صلى الله عليه وسلم، كُلَّمَا انْقَضَتْ قِصَّةٌ قَالَ‏:‏ أَمَّا بَعْدُ‏.‏

Hisham ibn 'Urwa said, "I saw some of the letters of the Prophet, may Allah bless him and grant him peace. After the introduction he said, 'Following on from that'"
