Al-Waadih Fee Usool ul-Fiqh by Muhammad Hussein Abdullah

Al-Ijtihaad is Fard ‘Ala-l-Kifaayah (An obligation of sufficiency) and consequently it is not permissible for a time period or era to be free of a Mujtahid who is capable of deducing Ahkaam Shar’iyah for the issues (Masaa’il) and realities that newly arise. With the existence of a Mujtahid or more than one, in any given time period or era, the sin falls from the Muslims in that time. That is because new realities of life continuously arise and they require Ahkaam Shar’iyah that make clear what the position of the Muslims towards them should be. It is not possible to apply the Hukm of Allah upon them unless the Hukm of Allah in relation to them is known which makes it necessary for the Muslims to acquire knowledge of this Hukm from the Shar’iyah texts. Some of these texts have come in a clear and manifest manner which do not require Ijtihaad to be undertaken however others require examination and Ijtihaad in order to deduce the Hukm from them. For example, the Aayaat of the Mawaareeth (the inheritances) came providing detail for the Ahkaam however some of the Ahkaam Al-Juz’iyah (partial or branch rulings) within this area require understanding and effort to deduce or extract the ruling for the issue, like the Mas’alah (issue) of Al-Kalaalah for instance. That is because Abu Bakr (ra) was asked about Al-Kalaalah as mentioned in the Qawl of Allah (swt):

And he (ra) said: “I will say in respect to Al-Kalaalah that which is my opinion. If it is correct, it is from Allah and if it is wrong, then it is from me and from the Shaytaan. Al-Kalaalah: The one who has no father(s) or son(s)” (i.e. no ascendants nor descendants).

The obligation to judge and rule by what Allah (swt) has revealed upon the Muslims demands from them that they derive the Ahkaam from these Nusoos (texts) and as such Al-Ijtihaad is Fard upon those capable in every era and time i.e. it is a Fard Kifaayah (obligation of sufficiency). If some were to undertake and fulfil it then the obligation would fall from the rest. This is from the angle of the principle:

That is because referring to what Allah (swt) has revealed for judgment cannot be accomplished in every issue except by Ijtihaad. Indeed, the Messenger of Allah (saw) encouraged the undertaking of Al-Ijtihaad when he said:

And this is highlighted in what the Messenger of Allah (saw) said to Mu’aadh Bin Jabal (ra) when he sent him to be a judge in Yemen:

The Sahaabah (rah) were therefore performing Ijtihaad at the time of the Messenger of Allah (saw) and he approved of their performance of Ijtihaad, informing them that the one who makes the correct Ijtihaad will attain two rewards whilst the one who makes an error will attain one reward.

If the Mujtahid arrives through his Ijtihaad to a Hukm Shar’iy, then it is the Hukm of Allah in respect to him (Fee Haqqihi) and it is not permissible for him to abandon his Ijtihaad and act contrary to this Ijtihaad except in one of the following circumstances:

A – If the Imaam of the Muslims (Al-Khalifah) adopts a Hukm Shar’iy in an issue that is different to his Hukm, then he must follow the opinion of the Imaam. In the time of Abu Bakr’s Khilafah, he (ra) would divide the expenditures upon the Muslims equally without differentiation or preference whilst ‘Umar (ra) viewed that precedence in Islaam should be taken into consideration. However, ‘Umar (ra) abandoned his Ijtihaad in the era of Abu Bakr (ra) and adopted the adoption of the Khalifah. Then in the time of his Khilafah he applied his own Ijtihaad.

The Qaa’idah Ash-Shar’iyah states: ( Thecommand of the Imaam removes the dispute or difference) and ِِanother states: (The command of the Imaam is implemented openly and inwardly). This means that it is an obligation to follow the adoption of the Khalifah openly and secretly.

B – If by abandoning his Ijtihaad it led to the preservation of the unity of the Muslims like what ‘Uthmaan (ra) did when he was given the Bai’ah for the Khilafah in the case where he agreed to act in accordance to the Kitaab of Allah, the Sunnah of His Messenger and to follow the Ijtihaadaat of the two former Khalifahs; Abu Bakr and ‘Umar (rah). That was because the Muslims stipulated and made conditional upon the one they wanted to pledge allegiance to that he would follow the path of the two former Khaleefahs in respect to the 569

manner of ruling. Consequently, ‘Uthmaan made this concession in regards to leaving his Ijtihaad in order to preserve the unity of the Muslims.

C – Greater level of Knowledge: If the Mujtahid saw that there was another Mujtahid who was more knowledgeable than him, then he can leave his own personal opinion and follow the opinion of that Mujtahid. This used to happen at the time of the Sahaabah (rah) and so for instance, Abu Mousaa Al-Ash’ariy (ra) would leave his opinion for the opinion of ‘Ali Ibn Abi Taalib (ra) whilst Zaid used to leave his opinion for the opinion of Ubayy Bin Ka’b (rah).

D – If the error of the Mujtahid’s Ijtihaad becomes plain and clear to him, he must revise his position and act in accordance to his new Ijtihaad that he views to be more correct than the previous one.

The majority of the ‘Ulamaa have viewed that it is impermissible to partition Ijtihaad and so it is not permissible for the Mujtahid to make Ijtihaad in Al-Mu’aamalaat (societal transactions) and make Taqleed (imitation and following) in Al-‘Ibaadaat (acts of worship). That is because Ijtihaad and Taqleed are two opposing meanings that do not meet or come together within a single person.

Some of the Maalikiyah and some of the Hanaabalah in addition to the Zhaahiriyah said that Ijtihaad can be partitioned. Consequently, the one who has knowledge of the linguistic areas or disciplines of knowledge and Shar’iyah areas sufficient for him to derive the Hukm of a particular Mas’alah (issue), then he should make Ijtihaad in that and make Taqleed to others in other than that.

Many of the A’immah (Imaams) used to respond to questions by saying: ‘I don’t know’ (Laa Adriy) if they did not know the answer as has been reported from Al-Imaam Maalik and Al-Imaam Ash-Shaafi’iy amongst others.

Therefore, partitioning the Ijtihaad is permissible in accordance to the Shar’a.

Ijtihaad takes place in respect to the Nusoos that contain a Zhanniy (speculative) Dalaalah (indication or implication). As for the texts which contain a Qat’iy (definite) Dalaalah (implied meaning), then it is not permitted to undertake Ijtihaad in respect to them.

Also, Ijtihaad relates to deriving the practical Ahkaam Ash-Shar’iyah and does not take place in respect to the Aqaa’id (beliefs). That is because it is obligatory for the Aqeedah to be Yaqeeniy (certain and definite) i.e. Qat’iy Ath-Thuboot and Qat’iy Ad-Dalaalah (Definite in transmission and meaning). There is therefore no place for Ijtihaad to be undertaken in respect to it as it is prohibited for the Aqeedah to be taken by way of Zhann (speculation or that which is indefinite). Allah (swt) says:
