Hadith 17:261
25563. Abu al-Ahwas narrated to us, from Mansur, from Abu Wa'il, from Abdullah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "If there are three, then two should not whisper privately to the exclusion of one, for that would grieve him, until they mix with the people."
حدثنا أبو الأحوص عن منصور عن أبي وائل عن عبد الله قال قال رسول الله صلى الله عليه وسلم إذا كان ثلاثة فلا يتناجى اثنان دون واحد أجل أن يحزنه حتى يختلط بالناس
