In these recent couple of verses, and the following one, in order to make clear the situation of all groups from the point of being exempted or not in regard to participation in Holy Struggle, there have been defined some proper degrees. At first, it says: “There is no fault in the weak and the sick and those who find nothing to spend…” These three groups are excused in any law, and intellect and logic also prove their being exempted.
It is certain that in no instance Islamic laws are separate from intellect and logic. After that, the Qur’ān has stated an important condition for the commandment of their being excused. It implies that this is in the condition that they refrain no sincere benediction unto Allah and His Messenger.
“…so long as they are true to Allah and to His Messenger…” They should encourage the strivers through their own words and behaviour toward Holy Struggle, and to weaken the enemies’ spirit so that they prepare the elementary factors of their failure. Later, in order to state the reason of this subject, it says that such people are some benevolent men, and there is no way for blaming, scorning, punishing and taking to task the good-doers.
“Nor (is the task) on those unto whom, when they come unto you to provide them with mounts, you said: ‘I do not find means to carry you,’ they turned back and their eyes overflowed with tears of sorrow, for they did not find that which they should spend.”*** In this verse, the Qur’ān refers to the fourth group of those who were also exempted from the Holy Struggle. This group had no means to ride on and to participate in the Holy Struggle.
They went to the Prophet (S) to obtain it, but he did not have any mount to give them for carrying them. They had to come back from him while their eyes were full of tears. This tear was for the sorrow which originated from the lack of means to spend it in the way of Allah.
