As we trace the historical development of Fiqh showed different characteristic trends during different periods of political and socio-economic development. First, we can discern that the outstanding characteristic of Fiqh during the period of the Righteous Caliphs was its realism; that is, it was based on actual problems rather than on hypothetical or imaginary ones. This realistic form of Fiqh was later referred to in Arabic as al-Fiqh al-Waqi’ee (realistic Fiqh) to distinguish it from the hypothetical Fiqh advocated by the “Reasoning People” (Ahl ar-Ra’i) who came to prominence in Kufah, Iraq, during the time of the Umayyads.
Na biyu, ko da yake Khulafa Ar-Rashidun sun kasance, kamar yadda muka lura a sama, suna bin wasu hanyoyi don cimma hukunce-hukuncen shari'a, ba su ba, ko Sahabbai baki ɗaya, da suka kafa tsayayyun hanyoyin da za a bi a ko'ina cikin al'ummar Musulunci (Ummah); haka kuma ba su rubuta dokokin da suka samo asali daga hukunce-hukuncensu ba. Wannan faffadan tunani a fagagen da Shari'ah ba ta bayyana su sarai ba, yana nuna, da farko, girmamawar Sahabbai ga 'yancin ra'ayi a irin waɗannan al'amura. Irin wannan halin ya saɓa sosai da yadda wasu malamai na baya suka nuna tsauri. Na biyu, hakan ya dace da manufar Sahabbai ta ba da shawara ga talakawa su yi nazarin Alƙur'ani da kyau, ba tare da shagaltuwa da hukunce-hukuncen shari'a kan al'amuran da Alƙur'ani bai bayyana su ba.
Secondly, although the Righteous Caliphs tended, as we have noted above, to follow certain procedures to achieve legal rulings, neither they nor the Sahaabah as a whole prescribed set procedures to be followed throughout the Islamic nation (the Ummah); nor did they make a record of the laws resulting from their legal rulings. This open mindedness in areas not clearly defined by Sharee’ah reflects, in the first place, the Sahaabah’s respect for freedom of opinion in such matters. Such an attitude contrasts strongly with the appearance of rigidity on the part of certain later scholars. In the second place, it was in keeping with the Sahaabah’s policy of recommending for the masses the careful study of the Qur’aan without the distraction of legal rulings on matters not defined therein.
Hali na uku na fiqhu a wannan zamani ya shafi amfani da ra'ayin kai wajen yanke hukunce-hukuncen shari'a. Mafi yawan Sahabbai sun fi son manne wa ma'anonin zahiri na nassosin Alkur'ani da Sunnah. A matsayin al'ada gabaɗaya, sun guje wa bayar da fassarorin kansu. Ibn 'Umar, ɗaya daga cikin manyan malaman fiqhu a cikin Sahabbai waɗanda suka zauna a Madina tsawon rayuwarsu, ya bi wannan al'ada. A ɗaya ɓangaren kuma akwai wasu Sahabbai waɗanda suka fi son yin amfani da ra'ayin kai sosai a fagen da Alkur'ani ko Sunnah ba su yi bayani a kansa ba. Duk da haka, sun kasance masu taka tsantsan wajen danganta kurakuran da ke biyo baya ga kansu gaba ɗaya, domin kada su kawo raini ga shari'ar Musulunci. 'Abdullahi ɗan Mas'ud (wanda daga baya ya zauna a Iraƙi) ya wakilci wannan makaranta ta tunani.
A third characteristics of Fiqh in this period relate to the use of personal opinion in making legal rulings. The majority of the Sahaabah preferred to stick closely to the literal meanings of texts of the Qur’aan and the Sunnah. As a general practice, they avoided giving personal interpretations. Ibn ‘Umar, one of the leading jurists among the Sahaabah who remained in Madeenah all his life, followed this practice. On the other hand there were other Sahaabah who favored the wide use of personal opinion in areas undefined by either the Qur’aan or the Sunnah. However, they were careful to attribute resulting errors entirely to themselves, so as not to bring discredit to Islamic law. ‘Abdullaah ibn Mas’ood (who later settled in Iraq) represented this school of thought.
Halayya ta huɗu ta Fiqhu a zamanin Khulafa'u Ar-Rashidun ta shafi gyara wasu hukunce-hukuncen Shari'ah, saboda ɗaya daga cikin abubuwa biyu: ɓacewar dalilin kasancewar hukuncin, ko canjin yanayin zamantakewa.
The fourth characteristic of Fiqh in the period of the Righteous Caliphs concerns the modification of some laws of Sharee’ah, owing to one or another of two factors: the disappearance of the reason for the laws existence, or a change in social conditions.
Misali na farko shi ne hana da Khalifa ‘Umar ya yi wa al’adar bayar da kyautar kuɗi daga Baitul-Mali ga sababbin musulmi da kuma waɗanda ke karkata zuwa karɓar Musulunci. ‘Umar ya gabatar da dalilinsa cewa wannan al’ada an bi ta ne a farkon Musulunci lokacin da ake matuƙar buƙatar kowane irin taimako, amma yanzu babu sauran buƙatar neman magoya baya. ﷺ
Abu na biyu da aka ambata a sama (canjin yanayin zamantakewa) ya haifar da canji a dokar saki. Saboda yawan dukiyar da ta kwararo daga yankunan da aka ci kwanan nan, aure (ko da na mace ɗaya ko na mata da yawa) ya zama mai sauƙin yi, kuma saboda haka saki ya ƙara yawaita sosai har abin tsoro. Don hana cin zarafin saki, Khalifa ‘Umar ya canza wani bangare na dokar. A zamanin Annabi ﷺ, furta kalmomin saki uku a lokaci guda ana ɗaukarsa a matsayin saki ɗaya kawai, kuma ana iya mayar da shi.
An example of the first is the prohibition by Caliph ‘Umar of the practice of giving cash gifts from the central treasury (Bayt al-Maal) to newly converted Muslims and to those leaning towards the acceptance of Islaam. ‘Umar reasoned that the practice had been followed by the Prophet (s.w.) in the early stages of Islaam, when there was urgent need for all possible support, but that there was no longer any need to canvass for supporters. The second factor mentioned above (changing social conditions) prompted a change in the divorce law. Owing to the tremendous influx of wealth from newly acquired territories, marriage (both single and multiple) became easier to contract and, consequently, divorce became alarmingly more frequent. To discourage abuse of divorce, Caliph ‘Umar altered and aspect of the law. In the time of the Prophet (s.w.) the pronouncement of three divorce statements at any one time was considered to be merely one divorce statement and it was reversible.
Halifa 'Umar ya ayyana irin waɗannan furuci da yawa a matsayin waɗanda suke ɗaurarru don haka ba za a iya juya su ba.
Caliph ‘Umar declared such multiple pronouncements to be binding and therefore irreversible.
Na biyar, mazhabin a lokacin Khulafa’u Rashidun ya kasance guda ɗaya kuma yana da alaƙa kai tsaye da gwamnati, kamar yadda yake a zamanin Annabi ﷺ. Mazhabin kowane daga cikin halifofi shi ne mazhabin halifan kansa, domin halifa a kowane lokaci shi ne yake da ikon ƙarshe a dukkan hukunce-hukuncen shari’a da suka shafi Ijtihadi da Ijma’i. Saboda haka, hukunce-hukuncen da halifa ya fitar ta hanyar istidlali ba su taɓa fuskantar adawa a fili daga magadansa ba a lokacin rayuwarsa. Sai dai idan wani halifa ya hau mulki, sai mazhabinsa ya samu fifiko a kan na wanda ya riga shi, kuma hukunce-hukuncen wanda ya riga shi za a canza su domin su dace da ra’ayinsa.
Fifthly, the Madh-hab during the period of the Righteous Caliphs was unified and directly linked to the state as in the time of the Prophet (s.w.). The Madh-hab under each of the caliphs was that of the caliph himself since the caliph in each case had the final say in all legal decisions involving Ijtihaad of Ijmaa’. Consequently, deduced rulings made by a caliph were never openly opposed by his successors during his lifetime. However, when the succeeding caliph came to power, his Madh-hab would then be given precedence over that of his predecessor and the deduced rulings of his predecessor would be changed to conform to his opinion.
