The spirit of unity in the Islamic instructions is not restricted to the principle of Unity of God as the basis of all Islamic beliefs. Rather, even in the invitation of prophets and messengers and divine books, Islam considers all of them identical in view of principles, which only have some differences in perfection stages.
Of course, this spirit is also visible in the Islamic scientific ordinances, rules and regulations, because the subject of Islamic ordinances and regulations is only man (man on the condition of maturity and intellect), and there is no other condition.
All Islamic sorbs are common in this sense that they are warner and cause reflection:
اَقِمِ الصَّلوةَ لِذِکْرِی).
And perform the prayer of My remembrance.
And they have a disciplinary effect and lead to simplism and control of rebellious sensual desires, and educating man. This is the unique spirit of all Islamic sorbs.
Islamic sorbs are all performed in one language, and this is the sign of unity, not for being in Arabic language belonging to a particular nation, rather for being the language of inspiration (and in addition to other reasons, the selection of this language may be for its simplicity, extent of words, derivations, compounds and its special tone).
The spirit of unity is apparent in the Islamic sorbs, specially in congregational sorbs, and in particular in pilgrimage which shows the highest manifestation of spirit of unity, and forms a unit in view of mentality, place and slogans which are expressed by different nations far from each other thousands of parasangs in view of body and soul. This situation has a particular splendor like that of unique system of the world of creation. Basically, the color of Islam is the color of creation, and consequently it is in coordination with it.
The arrays of Islamic congregational prayers for a supposed observer, watching the earth from outside, resemble the concentric circles gathering around a center, and this indicates a perfect unity.
Islamic scales have been adopted based on natural scales as far as possible, which are identical for all, and there is no color of a special nationality, and for determination of some subjects, for instance, pace, palm and such like are used.
Islamic month and year are focused on the circulation of moon and sun (or more correctly circulation of earth around the sun), and they are identical for everybody, and there is no need to technical specialty for understanding them, and there is no difference in them save in view of difference in horizon, which is the natural property of different parts of the earth.
