The word “uzlet” is a term of Sufism in the sense of avoiding being together with people, to live by retiring apart. Although there are slight differences, the words of ‘vahdet'-being alone-, ‘halvet'- loneliness-, ‘inziva'- seclusion- are also used in that meaning. The words of ‘ihtilat'-social intercourse- and ‘hiltat' -intermingling - are the opposite of it . ( Suleyman Uludag, The Treatise of Kushayri, p: 240)
The aim of solitude of the person is, to avoid sins and the things that will lead them. But The Sufis say that the thing that is appropriate for such a person is to think that his aim of being a way from people is not to avoid their wickedness, but being of the people safe from his own badness.”
To avoid the preoccupation of Satan, a person who retires into should have the knowledge about belief and for being his worship accepted; he should have the knowledge that helps the performing of obligatory religious duties.
Muslim savants suggested different opinions about either solitude or intermingling is more superior. Imam Shafi and Ahmed b. Hanbel are of the ones who said that social intercourse is recommended in religion.
The essential thing in Islam is not to being far a way from people but welding with them. It is said that Hadrat Prophet declared as follows in one of his hadiths:
“A believer who is mixed with people and who endure their pains and cruelty is more virtuous than a believer who is not mixed with them and who does not bear their pressure.” (Suyuti, el-Camius, Sa?yr, II, 282). Indeed solitude that Sufis wanted is not permanently leaving people but it is to train nafs-carna mind- and turning among people again.
In his treatise, Kushayri , by indicating that the real solitude is not being a way from people but being a way from sins and says: “ Indeed solitude-uzlet- is leaving bad habits. The influence of solitude should be sought in leaving the bad qualities not leaving one's place. . So to the question of “ Who is sagacious one ” it was answered as “ the person who is both together and separate , that means a person who is together with people outwardly but who is separate from them in secret.
