Mukhallaqa pillar is one of the pillars of Masjid al-Nabi and the closest pillar to mihrab of Prophet(a), which was the place where incense was placed to perfume the Masjid al-Nabi. After changeing Qibla in the second year of Hijra/ 624 , the Prophet used to pray in front of this pillar for some time. Therefore, this pillar, which was the sign of the Prophet's prayer, was called the “ʿAlam(sign) pillar”.
the sources mentions that blessing this pillar is recommended and prayers next to it is fulfilled. It is also reported that Imam Rida(a) prayed 6 or 8 rakats next to this pillar.
