The Messenger of Allah (ﷺ) was asked: What deed could be an equivalent of Jihad in the way of Allah, the Almighty and Exalted? He answered: You do not have the strength to do that deed. The narrator said: They repeated the question twice or thrice. Every time he answered: You do not have the strength to do it. When the question was asked for the third time, he said: One who goes out for Jihad is like a person who keeps fasts, stands in prayer (constantly), (obeying) Allah's (behests contained in) the verses (of the Qur'an), and does not exhibit any lassitude in fasting and prayer until the Mujahid returns from Jihad in the way of Allah, the Exalted.
As I was (sitting) near the pulpit of the Messenger of Allah (ﷺ), a man said: I do not care if, after embracing Islam, I do not do any good deed (except) distributing drinking water among the pilgrims. Another said: I do not care if, after embracing Islam, I do not do any good deed beyond maintenance service to the Sacred Mosque. Another said: Jihad in the way of Allah is better than what you have said. 'Umar reprimanded them and said: Don't raise your voices near the pulpit of the Messenger of Allah (ﷺ) on Friday. When prayer was over, I entered (the apartment of the Holy Prophet) and asked his verdict about the matter in which they had differed. (It was upon this that) Allah, the Almighty and Exalted, revealed the Qur'anic verse:" Do you make the giving of drinking water to the pilgrims and the maintenance of the Sacred Mosque equal to (the service of those) who believe in Allah and the Last Day and strive hard in the cause of Allah. They are not equal in the sight of God. And Allah guides not the wrongdoing people" (ix. 20).
If some persons of my Umma (were not to undertake the hardships of Jihad), and he (Abu Huraira) then narrated the rest of the hadith and then said: A journey undertaken for jihad in the evening or morning merits a reward better than the world and all that is in it.
