Few people keep your company, and even fewer are truly acquainted with you personally!
In The Name of Allah, The Most Merciful, The Bestower of Mercy.
Ibn Abbas, may Allah be pleased with him and his father, said, “Well-being and safety are ten parts; nine parts are found in silence (i.e. speak good or remain silent) and the tenth part is found in seclusion”. [1]
Malik Bin Deenaar, may Allah have mercy upon him, said, “The righteous people used to advise one another with three affairs: restraint of the tongue, seeking Allah’s forgiveness, and seclusion”. [2]
Al-Khattaabee, may Allah have mercy upon him, stated that the intent behind this [i.e. seclusion] neither means that a person abandons the obligatory gatherings [i.e. Salawaat, the Jumu’ah prayer and other gatherings where one is required to appear, etc], nor that one neglects the rights of the people [i.e. such as visiting people for the sake of Allah, helping them, responding to an invitation, etc] and the good customary practices established amongst the people (i.e. the ones not in opposition to the Shariah), nor does it mean that one refrain from replying to their greetings; rather seclusion necessitates abandoning excessive and increased intermingling for which there is no need. [3]
The Hidden One: Imam Muhammad Ibn Salih Al-Uthaymeen, may Allah have mercy upon him, said: He does not make himself manifest and does not give importance to manifesting himself amongst the people, to be pointed out or for people to speak about him. You find him between his house and his Masjid and vice versa; from his house to his relatives and his brothers, whilst being unnoticed, and making himself unnoticed. However, this does not mean that if Allah grants a person knowledge, he confines himself in his house and does not teach the people. This is in opposition to piety. Teaching the people is better for him than being confined in his house and not benefiting the people with his knowledge, or sitting in his house and not benefiting the people with his wealth; rather if the affair is between being conspicuous- to manifest himself or make himself visible, or hiding (i.e. without a need to make himself manifest), he chooses to hide; but if it is the case that he must make himself apparent, he has to make himself apparent. This is beloved to Allah [The Mighty and Majestic]. [4]
