Dought & clear, - The days of Tashreeq

What are the days of Tashreeq? What is special about them and
distinguishes them from other days?.
Praise be to Allaah.
The days of Tashreeq are the 11th, 12thand 13thof Dhu'l-Hijjah. There
are several verses and ahaadeeth which speak of their virtue:
1 – Allaah says (interpretation of the meaning):
"And remember Allaah during the appointed Days"
[al-Baqarah 2:203]
These are the days of Tashreeq. This was the view of Ibn 'Umar and
most of the scholars.
2 – The Prophet(peace and blessings of Allaah be upon him) said
concerning the days of Tashreeq: "They are days of eating, drinking
and remembering Allaah." Dhikr (remembering Allaah) is enjoined during
the days of tashreeq in several ways:
-Remembering Allaah immediately after the prescribed prayers by
reciting Takbeer. This is prescribed until the end of the days of
Tashreeq according to the majority of scholars.
-Remembering Him by sayingBismillaahandAllaahu akbarwhen slaughtering
the sacrificial animal. The time for slaughtering the hadiy and
udhiyah lasts until the end of days of Tashreeq.
-Remembering Allaah when eating and drinking. It is prescribed when
eating and drinking to sayBismillaahat the beginning, and to praise
Him (sayAl-hamdu Lillaah) at the end. According to the hadeeth
narrated from the Prophet(peace and blessings of Allaah be upon him):
"Allaah likes His slave when he eats something to praise Him for it,
and when he drinks something to praise Him for it." Narrated by
Muslim, 2734.
-Remembering Him by saying Takbeer when stoning the Jamaraat on the
days of Tashreeq. This applies only to the pilgrims on Hajj.
-Remembering Allaah in general. It is mustahabb to make a lot of dhikr
during the days of Tashreeq. 'Umar used to recite Takbeer in Mina in
his tent, and when the people heard him they recited Takbeer too and
Mina echoed with the sound of their Takbeer. Allaah says
(interpretation of the meaning):
"So when you have accomplished your Manaasik [rituals of Hajj],
remember Allaah as you remember your forefathers or with a far more
remembrance. But of mankind there are some who say: "Our Lord! Give us
(Your Bounties) in this world!" and for such there will be no portion
in the Hereafter.
201. And of them there are some who say: "Our Lord! Give us in this
world that which is good and in the Hereafter that which is good, and
save us from the torment of the Fire!""
[al-Baqarah 2:200-201]
Many of the salaf regarded it as mustahabb to make a lot of du'aa'
during the days of tashreeq.
The words of the Prophet(peace and blessings of Allaah be upon him),
"These are days of eating, drinking and remembering Allaah" indicate
that eating and drinking during the days of Eid are means that help
one to remember Allaah and obey Him; perfect gratitude for the
blessing means using it to help one obey and worship Allaah,
In His Book Allaah commands us to eat of good things and thank Him for
them. So whoever uses Allaah's blessings to commit sin is showing
ingratitude for the blessing of Allaah, so he deserves to have it
taken away from him.
3 – The Prophet(peace and blessings of Allaah be upon him) forbade
fasting on these days: "Do not fast on these days, for they are the
days of eating, drinking and remembering Allaah." Narrated by Ahmad,
10286; classed as saheeh by al-Albaani inal-Silsilah al-Saheehah,
3573.
See Lataa'if al-Ma'aarifby Ibn Rajab, p. 500.
O Allaah, help us to do righteous deeds and make us steadfast until
death; have mercy on us, O Most Generous Giver. Praise be to Allaah,
the Lord of the World.
