The Prophet ﷺ used to send commanders and messengers one after another
باب مَا كَانَ يَبْعَثُ النَّبِيُّ ﷺ مِنَ الأُمَرَاءِ وَالرُّسُلِ وَاحِدًا بَعْدَ وَاحِدٍ

Narrated 'Abdullah bin 'Abbas:
Allah's Apostle sent a letter to Khosrau and told his messenger to give it first to the ruler of Bahrain, and tell him to deliver it to Khosrau. When Khosrau had read it, he tore it into pieces. (Az-Zuhri said: I think Ibn Al-Musaiyab said, "Allah's Apostle invoked Allah to tear them (Khosrau and his followers) into pieces."
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنِي اللَّيْثُ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، أَنَّهُ قَالَ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ بِكِتَابِهِ إِلَى كِسْرَى، فَأَمَرَهُ أَنْ يَدْفَعَهُ إِلَى عَظِيمِ الْبَحْرَيْنِ، يَدْفَعُهُ عَظِيمُ الْبَحْرَيْنِ إِلَى كِسْرَى، فَلَمَّا قَرَأَهُ كِسْرَى مَزَّقَهُ، فَحَسِبْتُ أَنَّ ابْنَ الْمُسَيَّبِ قَالَ فَدَعَا عَلَيْهِمْ رَسُولُ اللَّهِ ﷺ أَنْ يُمَزَّقُوا كُلَّ مُمَزَّقٍ.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، حَدَّثَنَا سَلَمَةُ بْنُ الأَكْوَعِ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لِرَجُلٍ مِنْ أَسْلَمَ " أَذِّنْ فِي قَوْمِكَ ـ أَوْ فِي النَّاسِ ـ يَوْمَ عَاشُورَاءَ أَنَّ مَنْ أَكَلَ فَلْيُتِمَّ بَقِيَّةَ يَوْمِهِ، وَمَنْ لَمْ يَكُنْ أَكَلَ فَلْيَصُمْ ".
