The prime minister's compliment for Shah came at a BJP parliamentary party meeting, in which he again made his displeasure known at members skipping parliamentary proceedings, at times despite a whip. Modi also noted that the members had been cautioned against it on many occasions.
Referring to Shah's debut in the Rajya Sabha, Modi, in a lighter vein, said the BJP chief's presence in Parliament might ensure the attendance of the other members, the sources said.
He added that the prime minister praised Shah's strategy and tireless efforts, "like a common worker", to expand the footprints of the party in the country.
Modi said it was difficult to run the affairs of a ruling party as the government often faced a lot of questions.

He said the opposition party was in such a "poor shape" that it managed to win the seat by a margin of less than one vote due to desertion by its members.
According to the sources, he also indicated that the outcome of the election might be challenged in court.
The BJP has questioned the Election Commission's (EC) decision to annul two votes cast by rebel Congress members in favour of the saffron party's candidate.
He also told the MPs to ask the schools in their constituencies to conduct quiz contests in this regard.
