Kama ilivyofafanuliwa awali, Mujtahid ni mtu anayechunguza tatizo kwa kina na kutafuta suluhisho kutoka katika vyanzo vya Shari'ah. Hata hivyo, Mitume huleta Ujumbe, ambao unajumuisha Shari'ah. Kuna tofauti dhahiri kati ya maneno haya mawili. Mmoja huleta Shari'ah, wakati mwingine huenda kwenye Shari'ah ili kutoa hukumu. Pia, Nabii ﷺ aliongozwa na wahyi. Allah (SWT) anasema:

As defined earlier, a Mujtahid is a person who studies the problem thoroughly and seeks the solution from the sources of Shari‟ah. However, the Messengers, bring the Message, which includes the Shari‟ah. There is an apparent difference between the two terms. One brings the Shari‟ah while the other goes to the Shari‟ah to extract rulings. Also, Prophet (saw) was guided by the revelation. Allah (swt) says:

{Wala hasemi kwa matamanio yake. Hayo si chochote isipokuwa ni wahyi unaoteremshwa kwake.} (Surat An-Najm: 3-4)

“Nor does he speak of his desire. It is no less than revelation sent down to him.” (TMQ An-Najm: 3-4)
