Is it prescribed to raise the hands when reciting the adhkaar of morning and evening?

Question

Praise be to Allah.

It is not prescribed to raise the hands when reciting the
adhkaar of morning and evening, or when reciting adhkaar following the
prescribed prayers, because there is no evidence that doing so is
mustahabb.

The basic principle is that it is mustahabb to raise the
hands for every du’aa’, except at the times when the Prophet (peace and
blessings of Allaah be upon him) said du’aa’ but did not raise his hands,
such as the du’aa’ during the Jumu’ah khutbah when it is not a prayer for
rain (istisqa’), du’aa’ during tawaaf and saa’i, and du’aa’ following
prayer, whether what is meant by du’aa’ following prayer is du’aa’ before
the salaam or after it. The Prophet (peace and blessings of Allaah be
upon him) did not raise his hands at these times.

But if a person raises his hands in some places sometimes,
there is nothing wrong with that in sha Allaah.

See the answer to question no.
11543.

The scholars of the Standing Committee for Issuing Fatwas was
asked: Is du’aa’ after obligatory prayer Sunnah? Should the du’aa’ be
accompanied by raising of the hands? Is it better to raise the hands with
the imam or not?

They replied: Du’aa’ after the obligatory prayers is not
Sunnah if that is done by raising the hands, whether it is done by the imam
alone or the worshipper alone or by both of them together. Rather that is
bid’ah (innovation), because it is not narrated from the Prophet (peace
and blessings of Allaah be upon him) or from the Sahaabah (may Allaah be
pleased with them). As for saying du’aa’ without that, there is nothing
wrong with it because there are some ahaadeeth which speak of that. End

Fataawa al-Lajnah al-Daa’imah
(7/103).

Shaykh Ibn Baaz (may Allaah have mercy on
him) said: Raising the hands in du’aa’ is one of the means of having du’aa’
answered in any place. The Prophet (peace and blessings of Allaah be
upon him) said: “Your Lord is modest and concealing, and He too shy, if His
slave raises his hands to Him for them to come back to him empty.” And he
(peace and blessings of Allaah be upon him) said: “Allaah is Good and
only accepts that which is good. Allaah commanded the believers to follow
the same commandments as He gave to the Messengers. He says (interpretation
of the meaning):

‘O (you) Messengers! Eat of the Tayyibaat
[all kinds of Halaal (lawful) foods which Allaah has made lawful (meat of
slaughtered eatable animals, milk products, fats, vegetables, fruits)] and
do righteous deeds. Verily, I am Well-Acquainted with what you do’
[al-Mu’minoon 23:51]

‘O you who believe (in the Oneness of
Allaah — Islamic Monotheism)! Eat of the lawful things that We have provided
you with’ [al-Baqarah 2:172]

Then he mentioned a man who has travelled
on a long journey and is dishevelled and covered with dust; he stretches
forth his hands to the heaven, (saying) “O Lord, O Lord”, but his food is
haraam, his drink is haraam, all his nourishment is haraam, so how can he
du’aa’ be accepted?” Narrated by Muslim in his Saheeh.

So He has made one of the means of du’aa’ being answered the
raising of the hands, and one of the reasons for du’aa’ not being answered
is the consumption of haraam food. This indicates that raising the hands is
one of the causes of du’aa’ being answered, whether on board a plane or
train or in a car or in a space ship or anything else. If a person says
du’aa’ and raises his hands, this is one of the causes of du’aa’ being
answered, except at the times when the Prophet (peace and blessings of
Allaah be upon him) did not raise his hands, such as the Jumu’ah khutbah,
when he did not raise his hands except when praying for rain, when he did
raise his hands. Similarly, between the two prostrations and before the
salaam in the last tashahhud, he (peace and blessings of Allaah be upon
him) did not raise his hands, so we should not raise our hands in these
places where the Prophet (peace and blessings of Allaah be upon him)
did not raise his hands. His doing something is evidence and his not doing
something is evidence. Similarly, after saying the salaam at the end of the
five daily prayers, when reciting the prescribed adhkaar, he did not raise
his hands so we should not raise our hands, following his example. As for
the places where he (peace and blessings of Allaah be upon him) did
raise his hands, the Sunnah is to raise the hands following his example, and
because that is one of the means of having du’aa’ answered. The same applies
to cases where the Muslim should call upon his Lord in du’aa’ and it is not
narrated whether the Prophet (peace and blessings of Allaah be upon
him) raised his hands or not; in these cases we should raise our hands
because of the ahaadeeth which indicate that raising the hands is one of the
means of having du’aa’ answered, as stated above.
