Ruling on singling out ‘Ashoora for fasting

Is it permissible to fast 'Ashoora' only without fasting the day
before orthe day after?.
Praise be to Allaah.
Shaykh al-Islam [Ibn Taymiyah] said: Fasting the day of 'Ashoora' is
expiation for one year, and it is not makrooh to single out this day
for fasting. Al-Fataawa al-Kubra, part 5.
In Tuhfat al-Muhtaaj by Ibn Hajar al-Haythami it says: There is
nothing wrong with fasting 'Ashoora' on its own. Part 3, Baab Sawm
al-Tatawwu'.
The Standing Committee was asked this question and replied as follows:
It is permissible to fast the day of 'Ashoora' on its own, but it is
better to fast the day before it or the day after it. This isthe
Sunnah that is proven from the Prophet(peace and blessings of Allaah
be upon him), as he said, "If I am still alivenext year, I will
certainly fast the ninth." Narrated by Muslim, 1134.
Ibn 'Abbaas (may Allaah be pleased with him) said: He meant, along
with the tenth.
And Allaah is the Source of strength.
