user111: I'm trying to find a specific story in where the Buddha spoke about the attainment of one Anagami lay person with a group of monks while praising his good qualities. Later, when those monks went for alms at his place, they informed him that the Buddha had spoken about his attainment. Then he asked the monks, if there were any lay persons present when the Buddha revealed it. The monks reported this back to the Buddha when they returned to the temple. Then the Buddha praised him again and said that is also another good quality of him.
I've heard this story several times in sermons, when the question comes up, whether an enlightened being would reveal his attainment to others.

Modesty, in particular, was evident in Hatthaka's character. While some take great pride in their wealth or are motivated by
  self-aggrandisement to convert others to the Dharma, Hatthaka was
  always quiet and unassuming. He did all he could to interest people in
  the Dharma purely out of concern for them, not to make a name for
  himself. On another occasion, when the monks told Hatthaka that the
  Buddha had praised his many good qualities, he said, "I hope there
  were no lay people present when the Lord did this." The monks assured
  him that there were none and later when they told this to the Buddha,
  he said, "Well done, well done. That man is genuinely modest. He does
  not like his good qualities to be known by others. Modesty is another
  of Hatthaka's good qualities."[ N10 ]


As background the following are present on the same page.



Another eminent lay disciple was Hatthaka of Alavi, a son of the ruler of Alavi. Hatthaka first met the Buddha as he was walking one
    winter evening. Surprised to see this lone ascetic in just one thin
    robe and sleeping on the hard ground, Hatthaka asked the Buddha, "Are
    you happy?" The Buddha replied, "Yes, I am happy." "But sir," Hatthaka
    asked, "the ground is hard and the wind is cold, how can you be
    happy?" The Buddha asked: "Despite living in a cosy, well-thatched
    house, with a comfortable bed and two wives to look after him, is it
    possible that due to greed, anger, fear or ambition that a man might
    feel unhappy?" "Yes," answered Hatthaka, "that is quite possible."
    "Well," said the Buddha, "I have got rid of all greed, anger, fear and
    ambition, so whether I sleep here or in a cosy house, I am always
    happy, always very happy.[ N8 ]



Hatthaka was famous not so much for his generosity or his knowledge of Dharma, but for his ability to attract people to the
  Dharma. Once he brought five hundred people, all obviously keen to
  practise the Dharma, to see the Buddha who asked him: "How do you
  manage to interest so many people in the Dharma?" Hatthaka answered:
  "Lord, I do it by using the four bases of sympathy, which you yourself
  taught me. When I know that someone can be attracted by generosity, I
  am generous. When I know that they can be attracted by kind words, I
  speak to them with kindness. When I know that they can be attracted by
  doing them a good turn, I do them a good turn, and when I know they
  can be attracted by treating them equally, I treat them with
  equality." Obviously, when people attended talks on Dharma organised
  by Hatthaka, they always received a warm personal welcome that made
  them feel liked and respected, and so they would come again, gradually
  getting interested in the Dharma. The Buddha praised Hatthaka for his
  skill. "Well done, Hatthaka, well done, this is the way to attract
  people." After Hatthaka had left, the Buddha said to the monks:
  "Consider it true that Hatthaka of Alavi is possessed of these eight
  marvellous and wonderful qualities. He has faith, virtue,
  conscientiousness and fear of blame, he is learned, generous, wise and
  modest."[ N9 ]


Thank you for the question.

"No, friend, there were no white-clad householders there."
"It's good, sir, that there were no white-clad householders there."
