Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا هُشَيْمٌ، عَنْ مَنْصُورٍ، عَنِ ابْنِ سِيرِينَ، - قَالَ أَحْمَدُ قَالَ مَرَّةً يَعْنِي هُشَيْمًا - عَنْ بَعْضِ وَلَدِ الْعَلاَءِ أَنَّ الْعَلاَءَ بْنَ الْحَضْرَمِيِّ كَانَ عَامِلَ النَّبِيِّ صلى الله عليه وسلم عَلَى الْبَحْرَيْنِ فَكَانَ إِذَا كَتَبَ إِلَيْهِ بَدَأَ بِنَفْسِهِ .
Some of the children of al-Ala' ibn al-Hadrami said: Al-Ala' ibn al-Hadrami was the governor of the Prophet (ﷺ) at al-Bahrayn, and when he wrote to him he began with his won name.
