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
‘Uqba b. Malik reported the Prophet 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.
