Abdullah ibn-Umar (May Allah be pleased with him) reportedthat Prophet Muhammadsaid:
There are no greater days in sight of Allah
& in which righteous deeds are most beloved to him
than these ten days (of Dhull-Hijjah)
So, during this time recite a great deal of
Tahlil(saying La-ilah-ha-illalah)
{There is none worthy of worship except}
Takbeer (Allahu-Akbar) & Tamhid (Alhamdulillah)

Hadrat Anas Radi ALLAH Taala Anhu reported that the Messenger of Allah Peace And Blessings Be Upon Him has said, “Everything has a heart, and the heart of the Qur’an is Yasin. Allah records anyone who recites Yasin as having recited the Qur’an ten times.”
