Is the reward for the Ishraq prayer recorded for one who prays it in a musalla after the Fajr congregational prayer if the mosque is far away?

Remaining in the prayer area after Fajr prayer until sunrise is a confirmed Sunnah (definition) of the Prophet, peace and blessings be upon him, and it applies to anyone who prays anywhere. As for attaining the reward of a Hajj and Umrah (definition) for one who prays two rak'ahs after remaining there until Ishraq, this is a favor contingent upon one who prayed Fajr in congregation in the mosque, or one whose habit it was to pray in congregation but was prevented by an excuse.
