Every community needs a perfect leadership to guide them to the right and avoid them from the wrong.
Allah The Glorious Has ordered people to follow the prophets then their successors. The last successor of the Prophet Muhammad (SAWA) is Imam Al-Mahdi (AS) who is at present under occultation by order of Allah (SWT) because of certain circumstances. Imam Al-Mahdi (AS) himself ordered the followers of Ahlul Bayt (AS) to follow during his occultation the most learned pious Ulama. (Wasaa'il al-Shia, Volume 27, Page 131.
Some persons misunderstand the meaning of Taqleed and ask about its validity . We invite them to think :
1. Is it possible for any Muslim to claim that Allah, The Most Glorious wants to leave the Ummah with out guide during the occultation of the Infallible Imam ?
2. Who is the best to guide the Ummah better than the most learned about the teachings of Ahlul Bayt (AS) with piousness?
3. Who can guide the Ummah to Islamic rules on new issues during the occultation better that the most learned and pious, who are the Maraaje' of Taqleed?
No community can remain protected from deviation if they do not follow a pious leadership and there is no leadership in the whole world more pious than our Maraaje' of Taqleed who have the maximum knowledge about Islam and highest level of piousness.
Wassalam.
