What are the Days of Tashreeq and what are they used for? (Outside of Hajj)
Wa Alaikum As Salaam,
The days of Tashreeq are 11th, 12th, and 13th of Zul Hijja. These are the special days on which the pilgrims are required to remember Allah excessively. Those who are not pilgrims are required to recite Takbeers after the Farz Salaah on these days and also after the Farz Salaah of the 9th and 10th of Zul Hijjah.
These days occur only in Zul Hijja and are therefore connected to the season of Hajj. It does not occur outside the season of Hajj. Hence, these days cannot be used for anything outside the sacred season.
And Allah knows best,
