“素质”（Ahliyah）分为两类：责任能力（Ahliyah Wujoob）和行为能力（Ahliyah Adaa’）。

The Ahliyah is divided into two categories: Ahliyah Wujoob and Ahliyah Adaa’.

1 – 享有权利的资格（Ahliyah Wujoob）：这指的是人适合享有合法权利或承担义务的资格。这种资格从人作为胎儿在母亲子宫中时就已存在，之后经历婴儿期、儿童期，直至达到成年（即Baaligh，发育成熟）。因此，人在一生之中都享有权利（Huqooq），与他相关的各种律例也随之成立，例如继承的律例（Al-Irth），以及与其财产相关的天课（Az-Zakaah）律例等。

1 – Ahliyah Wujoob: This relates to the suitability of the human in respect to him having legitimate rights or rights being due upon him. This Ahliyah exists from the time that the human is a foetus in the womb of his mother, then as a baby, child and then Baaligh (i.e. adult/pubescent) Therefore, through life itself the human has rights (Huqooq) and Ahkaam are related to him like the Ahkaam of Al-Irth (inheritance) and Az-Zakaah in respect to his wealth amongst other rulings.

2 – 行为能力（Ahiyah Al-Adaa’）：这涉及人在承担其行为与言语所带来的责任（Takleef）方面的资格。当行为能力（Ahliyah）在履行义务（Adaa’）方面完全具备时，此种责任（Takleef）的条件是：成年（Al-Buloogh）、神智健全（Al-‘Aql）与具备能力（Al-Qudrah）。若行为能力在履行义务（Adaa’）方面不完整或有所欠缺，则仅与辨别能力（At-Tamyeez）相关，这一阶段始于儿童年满七岁，持续至其达到青春期（Al-Buloogh）为止。

2 – Ahiyah Al-Adaa’: This relates to the suitability of the human in regards to the Takleef in the case where he carries the responsibility of his actions and speech. The Shuroot of this Takleef in the case where the Ahliyah (suitability) is complete in respect to the performance (as a whole) are Al-Buloogh (adulthood), Al-‘Aql (sound mind) and Al-Qudrah (capability). If the Ahliyah is deficient or incomplete in respect to the Adaa’ (performance) then this relates to At-Tamyeez (age of discernment) alone and this starts when the child reaches the age of seven and lasts until he reaches the age of puberty (Al-Buloogh).
