1. We are not allowed to fast them, just like how we aren’t allowed to fast the days of Eid.
2. We must remember Allah abundantly in them with all established forms of thikr, especially the Takbeer of these days.

Our Prophet (PBUH) said: “They are days of eating, drinking and remembering Allah.”

Thikr (remembrance of Allah) happens in many ways especially during these days. From them:

1. Reciting the takbeer of these days generally.
2. Reciting the takbeer of these days after the obligatory prayers.
3. Reciting the takbeer (Allahu Akbar) when slaughtering the udhiyah (qurbani).
4. Reciting the takbeer (Allahu Akbar) when stoning the Jamaraat (for the hujjaaj of course).
5. Observing the athkaar (supplications) after Salah.
6. Observing the athkaar of the morning & evening.

And Allah knows best.

May Allah Almighty accept our deeds, and bless our days. Ameen.
