ليس على الأعمى حرج ولا على الأعرج حرج ولا على المريض حرج (48:17) بالانجليزي

(48:17) There is no blame on the blind, nor on the lame, nor on the sick (if they do not go forth to fight). *31 Allah will admit those who obey Allah and His Messenger to the Gardens beneath which rivers flow and will inflict a grievous chastisement on those who turn away.

Tafseer Abu-al-A'la Maududi

Page 513 English Traditional

*31) That is, the one who has a genuine excuse for not joining Jihad is not accountable, but if the able-bodied, strong people make excuses for not joining it, they cannot be regarded as sincere with regard to AIIah and His Religion, and they cannot be given the opportunity to take advantage of the gains as members of the Muslim community, but when time comes for making sacrifices for Islam, they should lag behind and seek the safety of their lives and properties." Here, one should know that two kinds of the people have been exempted from Jihad duty by the Shari ah: (1) Those who are not physically fit for Jihad. e.g. young boys, women, the insane, the blind and such patients as cannot perform military duties, and such disabled people as cannot take part in war; and (2) those for whom it may be difficult to join Jihad for other sound reasons, e.g. the slaves, or those persons who may be ready for Jihad but may not afford weapons of war and other necessary equipment, or such debtors who may have to pay their debts at the earliest opportunity and the creditors may not be willing to allow them more time, or such people whose parents (or a parent) might be alive, who stand in need of the children's help. In this regard, it should also be known that the children should not join Jihad without the permission of their parents if they are Muslims, but if they are non-Muslims it is not permissible for a person to stay away from Jihad in case they refuse permission.
