,Dought & clear - ,- Prayer When There is anEclipse - He missed Fajr prayer and found the congregation offering the eclipse prayer.

If a man comes late for Fajr prayer, can he join the imam whilst he is
offering the eclipse prayer?.
Praise be to Allaah.
If he knows that he is offering the eclipse prayer, then he should not
join him, because of the difference in nature between the two prayers.
Although the eclipse prayer is two rak'ahs, each rak'ah includes two
bowings, two standings and two recitations. So whoever does not
realize that the imam is offering the eclipse prayers and join the
imam with the intention of praying Fajrshould form the intention of
praying separately from the imam when he realizes that the imam is
offeringthe eclipse prayer. Then he should complete his prayer as Fajr
and then ifhe wants he may join the imam for whatever is left of the
eclipse prayer.
And Allaah is the Source of strength.
