Praise be to Allah.
If a person catches up with the tashahhud only with the imam in Eid prayer or prayer for rain, he should pray two rak’ahs after the imam says the salaam, doing in them as the imam did of takbeer, recitation, bowing and prostrating.
And Allah is the source of strength. May Allah send blessings and peace upon our Prophet Muhammad and his family and Companions. End quote.
