Qur'an 9:92 · At-Tawba

وَلَا عَلَى ٱلَّذِينَ إِذَا مَآ أَتَوْكَ لِتَحْمِلَهُمْ قُلْتَ لَآ أَجِدُ مَآ أَحْمِلُكُمْ عَلَيْهِ تَوَلَّوا۟ وَّأَعْيُنُهُمْ تَفِيضُ مِنَ ٱلدَّمْعِ حَزَنًا أَلَّا يَجِدُوا۟ مَا يُنفِقُونَ

(92) Nor [is there blame] upon those who, when they came to you for you to take them along, you said, "I can find nothing upon which to carry you."[497] They turned back while their eyes overflowed with tears out of grief that they could not find something to spend [for the cause of Allāh].
