What is the ruling on raising the hands when saying takbeer in the funeral prayer?


Praise be to Allah.

There is no difference of opinion among the scholars (may
Allah have mercy on them) concerning the fact that the Sunnah is to raise
the hands when saying the first takbeer of the funeral prayer. 

An-Nawawi (may Allah have mercy on him) said: Ibn al-Mundhir
said in his book al-Ishraaf wa’l-Ijmaa‘: They are unanimously agreed
that (the worshipper) should raise his hands when saying the first takbeer,
but they differed concerning the rest of it.

With regard to the other takbeers, the scholars (may Allah
have mercy on them) differed as to whether the hands should be raised or
not? 

In al-Mawsoo‘ah al-Fiqhiyyah (16/29) it says: He
should only raise his hands in the first takbeer, according to the Hanafis.
This was the view of Maalik and it is the more correct view according to
their madhhab. … The Shaafa‘is and Hanbalis said that it is Sunnah to raise
the hands with every takbeer. End quote. 

Ibn al-Mundhir favoured the view that the hands should be
raised with every takbeer. See al-Majmoo‘, 5/190 

Shaykh Ibn Baaz (may Allah have mercy on him) said: The
Sunnah is to raise the hands with all four takbeers, because it is proven
that Ibn ‘Umar and Ibn ‘Abbaas used to raise their hands with all the
takbeers. Ad-Daaraqutni narrated it in a marfoo‘ report from Ibn ‘Umar with
a jayyid isnaad.

Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) was
asked: Which is better, to raise the hands or not raise them in the funeral
prayer? 

He replied: The correct view is that raising the hands with
the takbeer in the funeral prayer is Sunnah with each of the takbeers, as
was clearly narrated from Ibn ‘Umar. Such tawqeefi matters (i.e., matters
that must be based on sound reports and cannot be subject to ijtihaad) can
only be determined on the basis of a text. In fact it is narrated that the
Prophet (blessings and peace of Allah be upon him) used to raise his hands
with every takbeer.

He also said: The correct view is that (the worshipper)
should raise his hands with every takbeer, because that is narrated in a
saheeh report from ‘Abdullah ibn ‘Umar (may Allah be pleased with him). With
regard to the view of some, that it should be done only in the opening
takbeer, this is the view of some of the scholars, but the correct view is
that it should be done with every takbeer. End quote from Majmoo‘
al-Fataawa, 17/134 

And Allah knows best.
