Sahih Muslim
وَحَدَّثَنِي حَجَّاجُ بْنُ الشَّاعِرِ، حَدَّثَنِي عَبْدُ الصَّمَدِ بْنُ عَبْدِ الْوَارِثِ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنِي عَلْقَمَةُ بْنُ مَرْثَدٍ، أَنَّ سُلَيْمَانَ بْنَ بُرَيْدَةَ، حَدَّثَهُ عَنْ أَبِيهِ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا بَعَثَ أَمِيرًا أَوْ سَرِيَّةً دَعَاهُ فَأَوْصَاهُ . وَسَاقَ الْحَدِيثَ بِمَعْنَى حَدِيثِ سُفْيَانَ .
Sulaiman b. Buraida repotted on the authority of his father that when Allah's Messenger (ﷺ) sent an Amir with a detachment he called him and advised him. The rest of the hadith is the same.
