At-Tawbah 9:92

Wala AAala allatheena ithama atawka litahmilahum qulta la ajidu maahmilukum AAalayhi tawallaw waaAAyunuhum tafeedumina addamAAi hazanan alla yajidoo mayunfiqoon

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].

Nor (is there any blame) on those who, when they came to you so that you might provide them with a carrier (that they could ride for Jihād ) and you said (to them), “I find no carrier to give to you”, went back with their eyes flowing with tears in grief, because they had nothing to spend.
