وَلَا عَلَى الَّذِينَ إِذَا مَا أَتَوْكَ لِتَحْمِلَهُمْ قُلْتَ لَا أَجِدُ مَا أَحْمِلُكُمْ عَلَيْهِ تَوَلَّوا وَّأَعْيُنُهُمْ تَفِيضُ مِنَ الدَّمْعِ حَزَنًا أَلَّا يَجِدُوا مَا يُنفِقُونَ ٩٢

Nor can (anyway be scoffed or blamed) those who presented themselves to your service (with the purpose) that you may arrange for them mounts (for fighting, because they did not possess any means of conveyance). So you said: ‘I (also) do not find any (additional means) to mount you on.’ Then (with your permission) they returned in such a state that their eyes were streaming with tears in grief (of being deprived of fighting in the cause of Allah: Alas!) They did not have (much) wealth, which they could spend (and manage to take part in the sacred fight). (9:92)
