The Prophet ﷺ said: "There is no deed done in any days that is better than it is in the ten of Dhul-Hijjah." They said, "O Messenger of Allah, not even jihad in the cause of Allah?" He said: "Not even jihad in the cause of Allah, except for a man who goes out with himself and his wealth in the cause of Allah, then returns with none of that at all." This is the wording of Shubah’s hadith.

In the narration of Abu Muawiyah, he said: The Messenger of Allah ﷺ said: "There are no days in which righteous action is more beloved to Allah than these days, meaning the ten days," and the rest is with its meaning.

أَنَّ النَّبِيَّ ﷺ قَالَ: «مَا الْعَمَلُ فِي أَيَّامٍ أَفْضَلَ مِنْهُ فِي عَشْرِ ذِي الْحِجَّةِ»، قَالُوا: يَا رَسُولَ اللهِ، وَلَا الْجِهَادُ فِي سَبِيلِ اللهِ؟ قَالَ: «وَلَا الْجِهَادُ فِي سَبِيلِ اللهِ إِلَّا رَجُلٌ خَرَجَ بِنَفْسِهِ وَمَالِهِ فِي سَبِيلِ اللهِ ثُمَّ لَا يَرْجِعُ مِنْ ذَلِكَ بِشَيْءٍ». لَفْظُ حَدِيثِ شُعْبَةَ.

وَفِي رِوَايَةِ أَبِي مُعَاوِيَةَ قَالَ: قَالَ رَسُولُ اللهِ ﷺ: «مَا مِنْ أَيَّامٍ الْعَمَلُ الصَّالِحُ فِيهَا أَحَبُّ إِلَى اللهِ مِنْ هَذِهِ الْأَيَّامِ يَعْنِي أَيَّامَ الْعَشْرِ»، وَالْبَاقِي بِمَعْنَاهُ.

The Messenger of Allah ﷺ used to fast the nine days of Dhu al-Hijjah, the day of Ashura, and three days of every month: the first Monday of the month, Thursday, meaning also another day. Abu Dawud also narrated it from Musaddad.

كَانَ رَسُولُ اللهِ ﷺ يَصُومُ تِسْعَ ذِي الْحِجَّةِ، وَيَوْمَ عَاشُورَاءَ، وَثَلَاثَةَ أَيَّامٍ مِنْ كُلِّ شَهْرٍ: أَوَّلَ اثْنَيْنِ مِنَ الشَّهْرِ، وَالْخَمِيسَ، تَعْنِي: وَيَوْمًا آخَرَ. وَرَوَاهُ أَبُو دَاوُدَ عَنْ مُسَدَّدٍ.

I have never seen the Messenger of Allah ﷺ fasting during the ten ˹days of˺ Dhu al-Hijjah.

مَا رَأَيْتُ رَسُولَ اللهِ ﷺ صَائِمًا فِي الْعَشْرِ قَطُّ.
