The first ten days of Dhul-Hijjah

Abu Abdullah, the freed slave of Sayyiduna Abdullah bin Amr (may Allah be pleased with him), narrates: Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrated a hadith to us while we were performing tawaf of the House of Allah. He said that the Prophet (peace and blessings be upon him) said: "There are no days in which doing a deed is more beloved to Allah Almighty than (doing it in) these days." It was asked: "Not even fighting in the path of Allah?" The Prophet (peace and blessings be upon him) said: "Not even fighting in the path of Allah, except for the one who goes out with his life and his wealth and then does not return, until his very lifeblood is shed (that is, he attains martyrdom)." The narrator Abdah says: This refers to the (first) ten days (of Dhu al-Hijjah).

In one narration the wording is: I was with the Prophet (peace and blessings be upon him). Deeds were mentioned, and he said: "There are no days in which doing a deed is more beloved to Allah Almighty than (doing it in) these ten days." After that the narrator mentioned the hadith as before.

It was asked: "Not even fighting in the path of Allah?" The Prophet (peace and blessings be upon him) said: "Not even fighting in the path of Allah."

So during these days, say 'Subhan Allah' abundantly, say 'La ilaha illa Allah', say 'Al-hamdu lillah', and say 'Allahu Akbar'."

It was asked: "(Is spending) the same number of days in the path of Allah (not more virtuous)?" He said: "(Spending) the same number of days in the path of Allah does not (carry as much virtue), except for the one who rubs his face in the dust (that is, is martyred)."

She said: "O Messenger of Allah, is this exclusive to us, the People of the House (Ahl al-Bayt), or is it for us and for the Muslims as well?"

And say: 'Indeed, my prayer, my sacrifice, my life and my death are for Allah, the Lord of all the worlds. He has no partner; this is what I have been commanded, and I am one of the Muslims.'" Sayyiduna Imran (may Allah be pleased with him) said: "O Messenger of Allah, is this exclusive to you and the people of your house, since you are worthy of it, or is it general for the Muslims?"
