ولا على الذين إذا ما أتوك لتحملهم قلت لا أجد ما أحملكم (9:92) بالانجليزي

(9:92) Likewise there can be no ground for criticising those people who came to you in person and requested you to provide them with mounts. For when you said to them, "I am unable to provide you with mounts, they returned with heavy hearts, their eyes overflowing with tears: they were filled with sorrow that they had no means of going forth for Jihad at their own expense. *93

Tafseer Abu-al-A'la Maududi

*93) Such people as felt a strong urge for Jihad but could not join it because of some really genuine excuse, will be counted by Allah among those who actually took part in it, even though they could not join it in person and do anything practically for it. This is because they were sincerely grieved at their absence from Jihad for no fault of theirs, just as a man of the world would be grieved if he were deprived of some lucrative business or of some high profit. AIlah considers such a one as on duty, because his heart was serving in the Way of Allah, though he had been deprived of active service on account of some genuine excuse. The Holy Prophet, while returning from Tabuk, stated the same thing like this: "There are some people at Al-Madinah (at this time) who have been travelling and marching all along with you through every valley. Naturally the Companions to whom he was speaking were wonder struck at this. So they asked, "While staying at Al-Madinah?" He replied, "Yes! while staying at AIMadinah! This is because they were compelled by the circumstances to stay behind at AI-Madinah: otherwise they would certainly have accompanied you. "
