1) Usulul-Fiqhi, kamar yadda muka ambata a baya, yana wakiltar ka'idoji (Qawaa'id) da mujtahid yake bi wajen istinbaɗi (fitar da hukunce-hukuncen Shari'ah na aiki daga hujjojinsu na tsari) kamar ka'idar nan: 'Aiki da hujjoji biyu ya fi (ya fi dacewa) a kan barin ɗaya daga cikinsu.'

1) Usool ul-Fiqh, as we have mentioned, represents the principles (Qawaa’id) that the Mujtahid follows in the Istinbaat (extraction) of the practical Shar’iyah rulings from their detailed evidences like the Qaa’idah (principle): ‘Working with two evidences is better (more proper) than neglecting one of them’.

Alhali kuwa Fiqh shi ne ilimi (sanin) na hukunce-hukuncen shari'a masu amfani da aiki da aka karɓo daga shaidunsu na tsari, kamar: Khamr haramun ne, Al-Jihad kuma farilla ne. Tahara sharaɗi ne daga cikin sharuɗɗan ingancin Salla, kuma kamar haila mai hana aiwatar da Salla ne.

This is whilst Fiqh is the ‘Ilm (knowledge) of the practical Ahkaam Ash-Shar’iyah taken from its detailed evidences like: Khamr is Haraam, Al-Jihaad is Fard. Tahaarah is a Shart (condition) from the conditions of the validity of the Salaah and like Haid (menses) is a Maani’ (prevention) for the performance of the Salaah.

2) Usulul Fiqhi ya haɗa da nazari game da harshe da ƙa'idodinsa, domin waɗannan ƙa'idodi suna da muhimmanci ga Ijtihadi. Misali: nazari game da Haqeeqah (ma'ana ta zahiri) da Majaaz (ma'ana ta alama), ma'anonin Huroofil Jarr (haruffan jarr), Huroofush Shart (haruffan sharadi), da kuma Alfaazh (kalmomi) na gaba ɗaya, da sauran al'amura. Shi kuwa Fiqhu an takaita shi ga bayanin Hukmush Shar'iy wanda ya zama wajibi ga Mukallaf, misali: Salla farilla ce, Umrah sunna ce (mandoob), kuma riba haramun ce.

2) Usool ul-Fiqh includes studies in relation to the language and its principles because these principles are necessary for Ijtihaad. This is like: The studies about the Haqeeqah (literal) and Majaaz (metaphorical), the meanings of the Huroof Al-Jarr (prepositions), the Huroof Ash-Shart, and the general Alfaazh (expressions) amongst other matters. This is whilst Fiqh is restricted to the explanation of the Hukm Ash-Shar’iy that is a requirement of the Mukallaf like: The Salaah is Fard, ‘Umrah is Sunnah (Mandoob) and Ribaa is Haraam.

3) Usulul Fiqhi yana nazari ga Dalilan Shari'a na gaba ɗaya kamar Alƙur'ani, Sunnah, Qiyas da Ijma'i, dangane da tabbatar da cewa sun fito daga Allah. Sannan yana nazari ga abin da ke cikinsu ta fuskar ƙa'idoji da sifofi kamar: Al-Khusus da Al-'Umum (na musamman da na gaba ɗaya), Al-Mutlaq da Al-Muqayyad (wanda ba a takaita ba da wanda aka takaita), Al-Mujmal (na gaba ɗaya wanda ba a yi bayani dalla-dalla ba) da Al-Bayan (bayani), da An-Naskh (soke hukunci).

3) Usool ul-Fiqh examines the Ijmaaliy Shar’iy Daleel like the Qur’aan, Sunnah, Qiyaas and Ijmaa’ in respect to establishing that it has come from Allah and then it examines what came within it in terms of principles and forms like: The Khusoos and the ‘Umoom (specific and general), the Mutlaq and the Muqayyad (unrestricted and restricted), Al-Mujmal (general/un-detailed) and Al-Bayaan (explanation) and An-Naskh (abrogation).

Yayin da Fiqh ke nazari a kan Daleel Al-Juz'iy (hujja ta ɓangare) wanda ke nuna ko ya jagoranci zuwa ga takamaiman Hukunci game da wani lamari ko aiki, don mukallaf ya bi shi. Misali, zai yi nazari a kan Aayah:

This is whilst Fiqh examines the Daleel Al-Juz’iy (partial evidence) that guides to or indicates a specific Hukm for a matter or an action for the purpose of the Mukallaf abiding by it. So for example it will examine the Aayah:

Ayar:

And the Aayah:

Kuma Hadisi:

And the Hadeeth:

Kuma ijma'in Sahabbai game da jinkirta binne Manzon Allah ﷺ har sai da suka yi mubaya'a ga wani Khalifa daga cikinsu.

And the Ijmaa As-Sahaabah in respect to delaying the burial of the Messenger of Allah (saw) until after they had pledged allegiance to a Khalifah from amongst them.

Wannan ana yi ne domin a samo Hukm Ash-Shar'iy daga kowace Daleel (hujja).

That is done in order for the Hukm As-Shar’iy to be taken from each Daleel (evidence).

Manufar Usulul-Fiqh ita ce amfani da ka'idojinsa a kan dalilai na tafsili don sanin hanyar da ake fitar da hukunce-hukuncen shari'a na aiki (al-Ahkaam ash-Shar'iyyah al-'amaliyyah) daga gare su.

4) The aim of Usool ul-Fiqh is the application of its principles upon the detailed evidences to arrive to the manner of how the practical Ahkaam Ash-Shar’iyah are extracted.

Yayin da manufar Fiqhu ita ce bayyanawa da aiwatar da Ahkaamu Ash-Shar'iyyah a kan ayyukan mutane da maganganunsu, kuma ita ce sanar da kowane Mukallaf umarnin Allah Ta'aalaa da abin da Ya hana, domin Mukallaf ya bi shi a cikin ayyukansa.

This is whilst the aim of Fiqh is to explain and apply the Ahkaam Ash-Shar’iyah upon the actions of the people and their speech and it is to make every Mukallaf aware of the commands of Allah Ta’Aalaa and what He has forbidden, so that the Mukallaf can adhere to it in his actions.
