Praise be to Allaah.
If you enter the mosque
when the imam has stood up from bowing, then you should say the dhikr that
is prescribed at this point, which is Rabbana wa laka’l-hamd, and you should
not say the opening du’aa’, because its place is the beginning of the
prayer, and you should not say A’oodhu Billaahi min al-shaytaan il-rajeem,
because its place is before recitation.
Al-Bukhaari (689) and
Muslim (411) narrated from Anas (may Allaah be pleased with him) that the
Messenger of Allaah (peace and blessings of Allaah be upon him) said:
“The imam has been appointed to be followed, so when he says takbeer, then
say takbeer; when he prostrates, then prostrate; when he rises, then rise,
and when he says, Sami’a Allaahu liman hamidah, then say Rabbana
wa laka’l-hamd. And if he prays sitting, then you should all pray

Shaykh Ibn ‘Uthaymeen (may
Allaah have mercy on him) was asked: If I join the imam when he is bowing,
when I stand up for the second rak’ah should I recite the opening du’aa’ or
He (may Allaah have mercy
on him) replied: If a person who joins the prayer late joins the imam when
he is bowing, then he should say the opening takbeer first (takbeer
al-ihraam) before bowing, then he should bow, but in this case if he says
the takbeer for bowing it is better, but if he does not say it, it does not
matter. This is the view of the scholars (may Allaah have mercy on them).
Then when he gets up for the second rak’ah, he should not say the opening
du’aa’ because the opening du’aa’ should only be said at the beginning of
the prayer, and the beginning of the prayer has already passed. It is a
Sunnah and he has missed its place, so he should not make it up at a point
which is not the right place for it. But he should seek refuge with Allaah
from the accursed shaytaan before reciting. End quote from Fataawa Noor
To sum up: If a person
catches up with the imam at some point, he should recite the dhikr that is
prescribed at that point, such as if he catches up during the sitting
between the two prostrations, he should say Rabb ighfir li, and if he
catches up during the tashahhud he should recite it, and so on.
