in the background of time and space

One of the reasons the glorious religion of Islam has lasted and was the seal of the prophethood is the struggle (Ijtihad) and deduction and in other word learning religion. The religious authority (Mujtahid) taking the principles of deduction into account and referring the changing offshoots to stable principles respond positively to the needs of his era and offer the due solutions for the Islamic community. None-theless, the general guidelines of Islamic rulings are stable, unchanging and limited but every epoch has its own particular requirements that cannot be met with-out struggle (Ijtihad). Thus, the article has also come up with the role of time and space in struggle and the way these two elements affected the Ijtihad.
