Wearing a turban belongs to the tradition of Sayyiduna Rasoolullah (sallal laahu alaihi wasallam), especially during the Salaah. The prayer that is performed wearing a turban carries more reward. The Shimlah of the turban should hang at the back between the two shoulders. The size of the Shimlah varies from person to person, but it should not be too long to be pressed under the buttocks while sitting. Some people do not hang Shimlah. This is against the Sunnah of Rasoolullah (sallal laahu alaihi wasallam). Amamah should be tied up in standing position and should be untied in the same manner. A cap can be worn under the Amamah. The Glorious Prophet of Allah (sallal laahu alaihi wasallam) said: “The very distinction between the pagans and us is that they tie only turban while we tie turban over a cap.”
According to “Mirqat”, the commentary on “Mishkat”, the Glorious Prophet of Islam (sallal laahu alaihi wasallam) used to wear Amamah of two sizes one small Amamah of seven arm-lengths, the other big Amamah of twelve arm-lengths.
Some people use bed sheets and prayer-mats, which contain inscriptions or couplets or the pictures of Mecca and Madina. The usage of such things is unlawful. The dining cloth and pillow covers containing inscriptions should also be avoided.
