In the Name of Allah, Most Merciful and Compassionate
The first ten days of Dhu’l Hijjah are blessed days: Allah Most High Himself swore by them in the Qur’an:
“By the Dawn,
and the Ten Nights…”
[Qur’an, Surat al-Fajr, 89.1-2]
The commentators generally concur that the ten nights refers, ‘the first ten days of Dhu’l Hijjah,’ as one may find in Shaykh al-Islam Abu Su`ud’sIrshad al-`Aql al-Salim ila Mazaya al-Qur’an al-Karim [famous as Tafsir Abi al-Su`ud, 9.153] or in Tafsir al-Jalalayn.
Imam Ahmad and Nasa’i report from the Mother of Believers, Sayyida Hafsa (Allah be pleased with her) that, “The Messenger of Allah (blessings and peace be upon him) did not leave four matters: Fasting `Ashura [10th of Muharram], [during] the ten days [of Dhu’l Hijja], and three days of each month.”
