This was said by David Coleman Headley, prime accused in the Mumbai case, before a Chicago court during questioning by Rana's attorney Patrick W Blegan.
Rana, a Pakistani Canadian, was not able to go ahead with his plans as it was against the ideals of Lashkar-e-Taiba, who opposed such a move.
Headley, who introduced himself to Rahul as a former Army ranger, also told the court that he had started liking him.
He in fact told him not to go to South Mumbai on Nov 26, the day LeT sent 10 terrorists for a major terrorist attack which over the next three days killed more than 160 people, Headley said.
Earlier, Headley conceded that there was once a talk of bringing Rahul to the tribal areas of Pakistan for "sightseeing".
However, he disagreed with the defence attorney that the plan was not to kill or kidnap him.
"We invite guests and do not kidnap them," Headley said.
However, he agreed that making friendship with Rahul was against the basic surveillance and espionage teachings that he had received from LeT and ISI.
