Allah commands His servant and Messenger, Muhammad , to himself fight in Jihad and not to be concerned about those who do not join Jihad. Hence Allah's statement,

﴿لاَ تُكَلَّفُ إِلاَّ نَفْسَكَ﴾

(you are not tasked (held responsible except for yourself,) Ibn Abi Hatim recorded that Abu Ishaq said, "I asked Al-Bara bin `Azib about a man who meets a hundred enemies and still fights them, would he be one of those referred to in Allah's statement,

﴿وَلاَ تُلْقُواْ بِأَيْدِيكُمْ إِلَى التَّهْلُكَةِ﴾

(And do not throw yourselves into destruction (by not spending your wealth in the cause of Allah)) He said, `Allah said to His Prophet,

﴿فَقَاتِلْ فِى سَبِيلِ اللَّهِ لاَ تُكَلَّفُ إِلاَّ نَفْسَكَ وَحَرِّضِ الْمُؤْمِنِينَ﴾

(Then fight in the cause of Allah, you are not tasked (held responsible) except for yourself, and incite the believers (to fight along with you)).'' Imam Ahmad recorded Sulayman bin Dawud saying that Abu Bakr bin `Ayyash said that Abu Ishaq said, "I asked Al-Bara', `If a man attacks the lines of the idolators, would he be throwing himself to destruction' He said, `No because Allah has sent His Messenger and commanded him,

﴿فَقَاتِلْ فِى سَبِيلِ اللَّهِ لاَ تُكَلَّفُ إِلاَّ نَفْسَكَ﴾

(Then fight in the cause of Allah, you are not tasked (held responsible) except for yourself,) That Ayah is about spending ﴿in Allah's cause.)
