Riyad as-Salihin, 1599

Ibn Mas'ud (May Allah be pleased with him) said:

The Messenger of Allah (ﷺ) said, "When three of you are together, two of you must not converse privately ignoring the third till the number increases, lest the third should be grieved." <b>[Al-Bukhari and Muslim]</b>.

وعن ابن مسعود رضي الله عنه أن رسول الله صلى الله عليه وسلم قال‏:‏ ‏

‏إذا كنتم ثلاثة، فلا يتناجى اثنان دون الآخر حتى تختلطوا بالناس، من أجل أن ذلك يحزنه‏

‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏

<b>Guidance from the Hadiths:</b><br> 1) It is forbidden for two persons to engage in private conversation while excluding the third because this harms the believers. The same applies when three persons do that to the exclusion of the fourth, or four to the exclusion of the fifth and so on, if the left out person is saddened by this.<br> 2) It is permissible to engage in private conversation when there is an assembly of people.<br> The Hadith manifests the comprehensiveness of Islam as it addresses all the aspects of life with its directives, instructions, and etiquettes. There is nothing, big or small, in the life of mankind except that Islam has explained and clarified it. So, we Muslims should rejoice in complying with the laws of our great religion.
