their lives are greater in rank before Allah. It is they who are triumphant. (20) Their Lord gives them glad tidings of mercy from Him, His good pleasure, and gardens in which they shall enjoy lasting bliss. (21) They will abide there forever. Indeed, with Allah is a tremendous reward.” [al-Tawba: 19–22]
And His words:
“Believers, whoever among you turns back from his faith, Allah will bring forth a people whom He loves and who love Him, humble toward the believers and mighty against the disbelievers. They wage jihad in the cause of Allah and fear no critic’s censure. That is Allah’s grace, which He grants to whomever He wills. Allah is All-Encompassing (1).” [al-Mā'ida: 54]
And He, exalted is He, said:
“That is because neither thirst, fatigue, nor hunger afflicts them in the cause of Allah; nor do they tread any ground that enrages the disbelievers or inflict any injury upon an enemy, without a righteous deed being recorded to their credit thereby. Indeed, Allah does not allow the reward of those who do good to be lost. (120) Nor do they spend any sum, small or large, or cross any valley, without it being recorded to their credit, so that Allah may reward them according to the best of what they used to do.” [al-Tawba: 120–121]
Thus He mentioned both what results from (2) their deeds and the deeds they perform directly.
The command (3) to wage jihad and the mention of its virtues in the Book and the Sunnah are too extensive to enumerate. For this reason, jihad is the best voluntary act a person can undertake. By scholarly consensus, it is superior to Hajj and Umrah, and to voluntary prayer and fasting, as indicated by the Book and the Sunnah. The Prophet ﷺ even said: “The head of the matter is Islam, its pillar is prayer, and its pinnacle is jihad.” (4)
