Praise be to Allaah.
It is well known that many shar‘i rulings were introduced in
stages, paying attention to people’s circumstances at the time of the
revelation. So something may have been mustahabb at the beginning, then it
became obligatory, or it may have been permitted then it was forbidden, or
vice versa.
What matters is the ultimate ruling.
In Saheeh al-Bukhaari (989) it was narrated that
Shihaab az-Zuhri said: What is to be adopted is the latest action of the
Prophet (blessings and peace of Allah be upon him).
And Muslim (1113) narrated it from him as follows: The
Companions of the Messenger of Allah (blessings and peace of Allah be upon
him) used to follow the latest instructions.
According to another version: They used to follow the latest
command, regarding it as abrogating others and as being the one to be
followed.
This that was stated by az-Zuhri is what was followed by the
majority of scholars: so the later of two shar‘i texts is what is to be
followed, as the shar‘i rulings came one after another and many obligatory
duties and rulings were changed at later stages.
But this principle is only to be applied when it is difficult
to reconcile between shar‘i texts in any possible way. However, if it is
possible to reconcile between them, then this reconciliation is to be given
precedence over the other approach (which is to adopt one and reject the
other).
One of the well-established guidelines among the scholars is
that reconciling between two texts takes precedence over adopting one and
rejecting the other (after examining the soundness of both). Or in other
words: considering two reports and adopting both is better than adopting one
and rejecting the other.
So adopting all texts is to be given precedence over
following some and rejecting others.
Al-Haafiz ibn Rajab said: If it is possible to reconcile
between them and act upon all of them, it is obligatory to do so and it is
not allowed to claim that one abrogates another. This is a rule that is to
be applied all the time.

Al-Haafiz Ibn Hajar sad: Reconciling is preferable to
adopting one and rejecting another (after examining the soundness of both),
according to the consensus of the scholars of usool.

If it is not possible to reconcile between two shar‘i texts
in any acceptable way, then the later text is to be followed in that case,
and is regarded as abrogating the earlier text.
If it is not known which is the earlier text and which is the
later text, then the scholars have to decide which has greater credibility,
and there are many ways of determining that, which the scholars have
discussed in detail in the books of Usool. For more information on that
please see al-Bahr al-Muheet by az-Zarkashi, 4/442, and Irshaad
al-Fuhool by ash-Shawkaani, 2/264
An-Nawawi said: If two hadeeths appear to contradict one
another, then there is no option but to reconcile between them or determine
which is more credible. That should only be done by scholars who have
knowledge of both fiqh and hadeeth and scholars of usool who have
great knowledge in the field, who are able to detect subtleties of meaning
and are well versed in that. Any scholar of that calibre will not find it
difficult to do that, except in rare cases.
Hadeeths that appear to contradict one another are of two
types:
-1-
Those that can be reconciled, in which case that is what must
be done and both must be followed and acted upon. Whenever we can find a
more useful interpretation of a text, then we should adopt that
interpretation, and we should not decide that one abrogates the other when
it is possible to reconcile between texts, because when a text is abrogated
it means that one of the two hadeeths is being dismissed and is no longer
being followed.
-2-
Those that contradict one another in such a way that it is
not possible by any means to reconcile between them. If we know that one of
them abrogates the other, then we must give it precedence. Otherwise we
should strive hard to work out which of the two is more credible, such as by
examining the number and calibre of narrators and all other means of
determining credibility, of which there are nearly 50 ways that were
compiled by al-Haafiz Abu Bakr al-Haazimi at the beginning of his book an-Naasikh
wal-Mansookh.

To sum up:
If two shar‘i texts contradict one another, the first thing
we must do is try to reconcile between them in an acceptable manner. If that
is not possible then we should follow the later of the two texts. If it is
not known which is the later one, we should examine them to find out which
report is more credible and adopt it.
It is essential to note that the methodology of the fuqaha’
in reconciling between shar‘i texts may differ in application from one
faqeeh to another. Some of them may find a way to reconcile the texts,
whilst others may think that reconciling between two hadeeths is farfetched,
so they may decide that one abrogates the other or they may examine them in
order to determine which is more credible, and so on.
And Allah knows best.
