Today, 15th Rabiul Awwal, First Masjid of Islam came into Existence

Masjid-e-Quba 

This was the first Masjid that the Prophet of Allah (SAW) built on his arrival from Makkah. Its foundations were laid by the Holy Prophet (s.a.) and he spent more than 20 nights here (after migrating) praying qasr while waiting for Imam Ali [a]. It is mentioned in the Qur'an as the mosque founded on piety and devoutness.

It is narrated that the Prophet of heard saying that if you say two Rak'ats Salaat in this Masjid you will get the sawaab of one Umrah.
May Allah give us opportunity to perform Umrah and Hajj and we pray in this historical Masjid.
