What fiqh is, and why answers differ
Fiqh is the human discipline of deriving practical law from revelation; sharia is the revelation itself. The distinction explains why the Quran is brief on the details of prayer while the books of fiqh are long: derivation, not invention, fills the space, and it is done by qualified jurists whose reasoning can be examined.
The Ja'fari school derives from the Quran, the practice of the Prophet and the Imams, consensus and reason, with the relative weight of those sources itself a matter of scholarly dispute. Because reasoning is involved, two authorities who both work in good faith can reach different conclusions on the same question — a difference the Quran anticipates when it speaks of a law and a path given to each community.
This site therefore never issues a ruling. The Ahkam pages lay out the question, the Quranic anchors and the fact that a legal answer exists, then open the official publication of the authority you chose. Where an official statement cannot be verified, the page says so and stops, which is the honest end of the platform's competence rather than a failure of it.
Quran
وَأَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ مُصَدِّقًۭا لِّمَا بَيْنَ يَدَيْهِ مِنَ ٱلْكِتَٰبِ وَمُهَيْمِنًا عَلَيْهِ ۖ فَٱحْكُم بَيْنَهُم بِمَآ أَنزَلَ ٱللَّهُ ۖ وَلَا تَتَّبِعْ أَهْوَآءَهُمْ عَمَّا جَآءَكَ مِنَ ٱلْحَقِّ ۚ لِكُلٍّۢ جَعَلْنَا مِنكُمْ شِرْعَةًۭ وَمِنْهَاجًۭا ۚ وَلَوْ شَآءَ ٱللَّهُ لَجَعَلَكُمْ أُمَّةًۭ وَٰحِدَةًۭ وَلَٰكِن لِّيَبْلُوَكُمْ فِى مَآ ءَاتَىٰكُمْ ۖ فَٱسْتَبِقُوا۟ ٱلْخَيْرَٰتِ ۚ إِلَى ٱللَّهِ مَرْجِعُكُمْ جَمِيعًۭا فَيُنَبِّئُكُم بِمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ
And We have revealed to you, [O Muhammad], the Book in truth, confirming that which preceded it of the Scripture and as a criterion over it. So judge between them by what Allah has revealed and do not follow their inclinations away from what has come to you of the truth. To each of you We prescribed a law and a method. Had Allah willed, He would have made you one nation [united in religion], but [He intended] to test you in what He has given you; so race to [all that is] good. To Allah is your return all together, and He will [then] inform you concerning that over which you used to differ.
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَطِيعُوا۟ ٱللَّهَ وَأَطِيعُوا۟ ٱلرَّسُولَ وَأُو۟لِى ٱلْأَمْرِ مِنكُمْ ۖ فَإِن تَنَٰزَعْتُمْ فِى شَىْءٍۢ فَرُدُّوهُ إِلَى ٱللَّهِ وَٱلرَّسُولِ إِن كُنتُمْ تُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ ۚ ذَٰلِكَ خَيْرٌۭ وَأَحْسَنُ تَأْوِيلًا
O you who have believed, obey Allah and obey the Messenger and those in authority among you. And if you disagree over anything, refer it to Allah and the Messenger, if you should believe in Allah and the Last Day. That is the best [way] and best in result.
وَمَآ أَرْسَلْنَا مِن قَبْلِكَ إِلَّا رِجَالًۭا نُّوحِىٓ إِلَيْهِمْ ۚ فَسْـَٔلُوٓا۟ أَهْلَ ٱلذِّكْرِ إِن كُنتُمْ لَا تَعْلَمُونَ
And We sent not before you except men to whom We revealed [Our message]. So ask the people of the message if you do not know.
