Surah At-Tawbah, Verse 92

وَلَا عَلَى ٱلَّذِينَ إِذَا مَآ أَتَوۡكَ لِتَحۡمِلَهُمۡ قُلۡتَ لَآ أَجِدُ مَآ أَحۡمِلُكُمۡ عَلَيۡهِ تَوَلَّواْ وَّأَعۡيُنُهُمۡ تَفِيضُ مِنَ ٱلدَّمۡعِ حَزَنًا أَلَّا يَجِدُواْ مَا يُنفِقُونَ٩٢

walā ʿalā alladhīna idhā mā atawka litaḥmilahum qul'ta lā ajidu mā aḥmilukum ʿalayhi tawallaw wa-aʿyunuhum tafīḍu mina l-damʿi ḥazanan allā yajidū mā yunfiqūna

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." 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].
