Mishkat al-Masabih
‘Uqba b. Malik reported the Prophet (ﷺ) as saying, “When I send out a man and he does not fulfil my command, are you unable to appoint in his place one who will fulfil my command?" Abu Dawud transmitted it.
وَعَن عقبَة بن مَالك عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «أعجزتم إِذا بعثت رجلا فَم يَمْضِ لِأَمْرِي أَنْ تَجْعَلُوا مَكَانَهُ مَنْ يَمْضِي لِأَمْرِي؟» . رَوَاهُ أَبُو دَاوُدَ
