Dought & clear, - Ruling on singling out ‘Ashoora for fasting

Is it permissible to fast 'Ashoora' only without fasting the day
before or the day after?.
Praise be to Allah
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.
InTuhfat al-Muhtaajby 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 is the
Sunnah that is proven from the Prophet(peace and blessings of Allaah
be upon him), as he said, "If I am still alive next 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.
