The first ten days of Dhul Hijjah are the best days and are more beloved to Allah. They are mentioned in Qur’an and sunnah because of their significance and benefits for Muslims. As in the following Hadith:
Narrated Ibn `Abbas:
The Prophet (PBUH) said, “No good deeds done on other days are superior to those done on these (first ten days of Dhul Hijja).” Then some companions of the Prophet (PBUH) said, “Not even Jihad?” He replied, “Not even Jihad, except that of a man who does it by putting himself and his property in danger (for Allah’s sake) and does not return with any of those things.” Sahih al-Bukhari
First: From the sayings of the predecessors: Ibn Hajar said: “The reason why the ten days of Dhul-Hijjah are privileged is the place where acts of worship gather, which are prayer, fasting, charity, and pilgrimage, and this is not possible in other obedience.
Second: Between the ten days of Dhul-Hijjah and the last ten days of Ramadan. The nights of the last ten days of Ramadan are better than the nights of the ten days of Dhul-Hijjah, and the days of the ten days of Dhul-Hijjah are better than the days of the ten days of Ramadan. Rather, it is preferred to consider its days, as it includes the Day of Sacrifice, the Day of Arafa, and the Day of Tarwiyah.
Third: Among the recommended actions in the first ten days of Dhul-Hijjah are the following:
⦁ Hajj and Umrah: Allah Almighty said: “The Hajj is well-known months” [Al-Baqarah: 197]. Al-Saadi said: What is meant by the most famous information according to the majority of scholars: Shawwal, Dhul-Qa’dah, and the ten days of Dhul-Hijjah, which are the ones in which Ihram for Hajj falls.
⦁ Fasting: The Messenger of Allah (PBUH) used to fast on the nine-ninths of Hajj and the Day of Ashura, and three days of every month, the first Monday of the month and Thursday.
The Messenger of Allah, may Allah’s prayers and peace be upon him, said: “Abu Qatadah Al-Ansari (may Allah be pleased with him) narrated, ‘The Messenger of Allah (PBUH) was asked about fasting on the day of Arafah (the 9th of the month of Dhul Hijjah).
He replied, “Fasting on the day of Arafah is an expiation for the preceding year and the following year.” He was also asked about fasting on the Day of Ashura (the 10th of the month of Muharram). He replied, “Fasting on the Day of Ashura is an expiation for the preceding year.”
The Messenger of Allah (PBUH) was also asked about fasting on Monday, and he replied, “This is the day on which I was born and the day on which I was sent (with the Message of Islam) and the day on which I received revelation.” Related by Muslim.
