Is it permissible to fast âAshooraâ 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.
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 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.
