Article 62
Jihad is obligatory upon the Muslims and military training is compulsory. Every male Muslim who has reached the age of 15 is obligated to undertake military training in order to prepare him for Jihad. Recruitment is an obligation of sufficiency.
The evidence for the article is from the Book and the Sunnah; Allah (swt) says.
“Fight them until there is no [more] fitnah and [until] worship is [acknowledged to be] for Allah.” (TMQ 2:193), and He (swt) said.
“Fight the leaders of disbelief.” (TMQ 9:12), and it is narrated from Anas that the Messenger of Allah (pbuh) said.
. » جَاهِدُوا الْمُشْرِكِينَ بِأَمْوَالِكُمْ وَأَيْدِيكُمْ وَأَلْسِنَتِكُمْ « .
“Fight the polytheists ( idol worshippers) with your wealth, hands and tongues” (reported by Ahmad and Al- Nasa’i with the wording from Al-Nasa’i, and both Al- Nasa’i and Al- Hakim authenticated it and Al-Dhahabi confirmed it). And Mu’adh b. Jabal said that the Prophet (phuh) said.
. » ذُرْوَةُ سَنَامِ الإِسْلاَمِ الْجِهَادُ فِي سَبِيلِ اللَّهِ « .
“The peak of Islam is Jihad in the cause of Allah” (reported by Ahmad).
When modern warfare requires military training in order to undertake what is required by the Shari’ah in terms of defeating the enemy and liberating lands, then this training would be obligatory in the same manner that Jihad is, in accordance with the Shari’ah principle. . )ما لا يتم الواجب إلا به فهو واجب( .
“That, without which the obligation cannot be accomplished, is itself an obligation”. This is because the order to fight encompasses training, since it is a general order. “and fight them”, which is an order to fight as well as an order to do whatever makes you capable of fighting. Above and beyond that, Allah (swt) said.
