Dought & clear, - It is mustahabb to fast the first eight days of Dhu’l-Hijjah for pilgrims and others

What is the ruling on fasting on the first eight days of Dhu'l-Hijjah
for the pilgrims? I know that it is makrooh for them to fast on the
Day of 'Arafah.
Praise be to Allaah.
Fasting on the first eight days of Dhu'l-Hijjah is mustahabb for
pilgrims and others, because the Prophet(peace and blessings of Allaah
be upon him) said: "There are no days in which good deeds are more
beloved to Allaah than these ten days." They said: O Messenger of
Allaah, not even jihad for the sake of Allaah? The Messenger of
Allaah(peace and blessings of Allaah be upon him) said: "Not even
jihad for the sake of Allaah, unless a man goes out with his self and
his wealth and comes back with neither." Narrated by al-Bukhaari (969)
and al-Tirmidhi (757), from the hadeeth of Ibn 'Abbaas (may Allaah be
pleased with him).
It says inal-Mawsoo'ah al-Fiqhiyyah(28/91): The fuqaha' are
unanimously agreed that it is mustahabb to fast during the first eight
days of Dhu'l-Hijjah, before the day of 'Arafah. The Maalikis and
Shaafa'is stated that it is Sunnah to fast on these days for the
pilgrim too. End quote.
It says inNihaayat al-Muhtaaj(3/207): It is Sunnah to fast the eight
days before the day of 'Arafah, as is stated inal-Rawdah, and that
applies equally to pilgrims and others, but it is not Sunnah for the
pilgrim to fast on the day of 'Arafah, rather it is mustahabb for him
not to fast then, even if he is able for it, following the example of
the Messenger(peace and blessings of Allaah be upon him), and so that
he will have more strength for du'aa'. End quote.
And Allaah knows best.
