Ibn `Abbas said, `The Appointed Days are the Days of Tashriq (11-12-13th of Dhul-Hijjah) while the Known Days are the (first) ten (days of Dhul-Hijjah).'' `Ikrimah said that:

(And remember Allah during the Appointed Days.) means reciting the Takbir - Allahu Akbar, Allahu Akbar, during the days of Tashriq after the compulsory prayers.

Imam Ahmad reported that `Uqbah bin `Amr said that Allah's Messenger said:

(The day of `Arafah (9th of Dhul-Hijjah), the day of the Sacrifice (10th) and the days of the Tashriq (11-12-13th) are our `Id (festival) for we people of Islam. These are days of eating and drinking.)

Imam Ahmad reported that Nubayshah Al-Hudhali said that Allah's Messenger said:

(The days of Tashriq are days of eating, drinking and Dhikr (remembering) of Allah.)

Muslim also recorded this Haith

We also mentioned the Hadith of Jubayr bin Mut`im:

(All of `Arafat is a standing place and all of the days of Tashriq are days of Sacrifice.)

We also mentioned the Hadith by `Abdur-Rahman bin Ya`mar Ad-Diyli:

(The days of Mina (Tashriq) are three. Those who hasten in two days then there is no sin in it, and those who delay (i.e., remain in Mina for a third day) then there is no sin in it.)

Ibn Jarir reported that Abu Hurayrah narrated that Allah's Messenger said:

(The days of Tashriq are days of eating and remembering Allah.)

Ibn Jarir reported that Abu Hurayrah narrated that Allah's Messenger sent `Abdullah bin Hudhafah to Mina proclaiming:

(Do not fast these days (i.e., Tashriq days), for they are days of eating, drinking and remembering Allah the Exalted and Most Honored.)
