Kilugha, neno "Shart" linamaanisha: Al-'Alaamah Al-Laazimah (Alama au sifa ya ndani au ya lazima).

Linguistically the Shart means: Al-’Alaamah Al-Laazimah (The inherent or necessary sign or characteristic).

Sharti ambalo ni Hukm Wad'iy kwa mujibu wa Istilaah (ufafanuzi wa kitaalamu) ya Wanausuli ni:

The Shart which is a Hukm Wad’iy according to the Istilaah (terminological definition) of the Usooliyeen is:

Ash-Shart ni kile kinachokuwa ni sifa (Wasf) inayokamilisha jambo linalowekewa sharti (Al-Mashroot), iwe Mashroot hiyo ni kitendo (Al-Fi'l) au sababu (Sabab) ya kitendo hicho.

Ash-Shart is that which is a Wasf (description) that completes the matter that is being conditioned for (Al-Mashroot) whether this Mashroot was the action (Al-Fi’l) or the Sabab of the action.

Mfano:

Example:

Al-Fi'l (kitendo): As-Salaah, na ni Mashroo' (jambo lenye masharti yaliyowekwa juu yake).

Al-Fi’l (the action): As-Salaah and it is the Mashroot (the matter having conditions placed upon it).

Al-Wudoo’: Ni sharti (sharti) na pia ni sifa (wasf) inayokamilisha vitendo vya Swalah. Kwa hiyo, ni sharti la kusihi (Sihhah) kwake.

Al-Wudoo’: It is the Shart (condition) and it is a Wasf (description) that completes the actions of the Salaah. It is therefore a condition for its Sihhah (validity).

Sababu ya Fi'l (chanzo cha tendo): Mali kufikia kiwango cha Nisaab. Nisaab ndiyo Sababu ya Zakaah.

Sabab ul-Fi’l (the cause of the action): The wealth reaching the level of the Nisaab. The Nisaab is the Sabab of the Zakaah.

Sharti ya Sababu (sharti la sababu): Kupita kwa mwaka mmoja juu ya Nisaab hii. Kwa hiyo, kupita kwa mwaka mmoja ni sharti kwa ajili ya Sababu (chanzo) ya tendo ambalo ni Nisaab ya Zakaah.

Shart As-Sabab (condition of the Sabab): The passing of a year upon this Nisaab. Therefore, the passing of a year is a condition (Shart) for the Sabab (cause) of the action which is the Nisaab of the Zakaah.
