In rainy weather, is it permissible to make Eid Salaat in the Masjid?
First and foremost, it is Sunnat Muakkadah to perform Eid Salaah in an Eidgaah or in an open field outside the locality as it is proven from the lifestyle and the practice of Rasoolullah Sallallahu Alayhi Wa Sallam and his companions.
Therefore, if one performs Eid Salah in a Masjid without a valid reason, when there are arrangements made for an Eidgaah, although his Eid Salah will be counted and valid, yet he will be going against the Sunnah and he will be sinful if this is done constantly.
Moreover, for reasons like rain, unavailability of Eidgaah etc. Eid Salaah can be conducted in the Masjid as this subject-matter is proven from Ahaadith. The crux of the Ahaadith is that Nabi Sallallahu Alayhi Wa Sallam used to go outside Madinah to perform the Eid Salah except one time in the rainy season where he led and performed the Eid Salah in the Masjid.
In a nutshell, Muslim communities should perform their Eid Salah in Eidgaah or in an open field outside the locality and revive this great Sunnah and can make arrangements for weak and sick people in the Masajid. Moreover, they should not establish more than one Eid Salah at one place without a valid reason.
