PM Modi informed the MPs about the dinner meeting at the BJP Parliamentary Party meeting and said he was doing so on behalf of Mr Shah who had gone to Meghalaya to attend the swearing-in ceremony of Chief Minister Conrad Sangma.
Party sources said it will be an occasion for the MPs - 332 in total - to visit the headquarters at Deen Dayal Upadhyay Marg and interact with their leaders.
The party is keen to maintain the momentum for the crucial assembly polls in Karnataka, where the Congress is in power.
