From Authentic sources Forty Rabbana Supplications
1. This du`a was read by Ibrahim and Ismail when they
completed the building of the Ka’bah.
2. The lesson is that a person must not be satisfied with actions
only. Rather, after the action, be humble and beg Allah to
accept it. This is taught from the action of Ibrahim Ismail
. After
completing such a lofty action he does not express pride, rather he
asks Allah
to accept the action.
