Is the reward for praying Fajr in congregation and engaging in remembrance until sunrise, followed by two rak'ahs, attained if the two rak'ahs are performed before the specified time of sunrise, even if the sky has brightened? And is the reward attained if the remembrance is completed on the way home?

"Whoever prays the dawn prayer in congregation, then sits remembering Allah until the sun rises, then prays two rak'ahs, will have the reward of a complete Hajj and 'Umrah." This is on condition of remaining in the prayer area after the Fajr prayer until the sun has risen, then performing the two rak'ahs. If a Muslim is prevented from waiting and intends to act upon the hadith, it is hoped that he will receive the reward for his intention, because "whoever intends to do a good deed and does not do it, a full good deed is recorded for him."
