The first ten days of Dhul Hijjah are venerated days. Allah swore by them in His Book, and swearing by a thing is indicative of its importance and great benefit. Good deeds during these days are beloved to Allah.
Allah ﷻ says,
وَالْفَجْرِ ۞ وَلَيَالٍ عَشْرٍ ۞
❝By the dawn; By the ten nights (i.e. the first ten days of the month of Dhulhijjah).❞ [al-Fajr 89:1-2].
Mujahid, al Suddi, al Kalbi say that the meaning of “ten nights” in this ayat are ten days of Dhul Hijjah.
