The shaking of the Throne at the death of Sa‘d ibn Mu‘aadh was only because of the joy of the Lord, may He be exalted; it was not a reflection of any imperfection

Firstly: 

Al-Bukhaari (3803) and Muslim (2466)
narrated from Jaabir (may Allah be pleased with him): I heard the Prophet
(blessings and peace of Allah be upon him) say: “The Throne shook at the
death of Sa‘d ibn Mu‘aadh.” 

Adh-Dhahabi (may Allah have mercy on him)
said:

This is mutawaatir (i.e., narrated by so
many from so many that it is inconceivable that they could all have agreed
upon a lie). I bear witness that the Messenger of Allah (blessings and peace
of Allah be upon him) said it.

(p. 89) 

He reported it in full in his book al-Fawaa’id
(16) from Abu Sa‘eed al-Khudri (may Allah be pleased with him) who said: The
Messenger of Allah (blessings and peace of Allah be upon him) said: “The
Throne shook at the death of Sa‘d ibn Mu‘aadh, because of the joy of the
Lord, may He be glorified and exalted.” 

Its isnaad was classed as jayyid by al-Albaani
in as-Saheehah (1288) 

In as-Sunnah by ‘Abdullah ibn
al-Imam Ahmad (1058) it says: It was narrated that al-Hasan said: The Throne
of the Most Merciful, may He be glorified and exalted, shook at the funeral
of Sa‘d ibn Mu‘aadh (may Allah be pleased with him). Al-Hasan interpreted it
as referring to joy at (the coming of) his soul. 

Secondly:

 We must accept the hadeeths that speak of
the attributes of Allah as they are; this also applies to what is connected
to those attributes of matters of the unseen. Al-Aajurri narrated in ash-Sharee‘ah
(3/1146) that al-Waleed ibn Muslim said: I asked al-Awzaa‘i, ath-Thawri,
Maalik ibn Anas and al-Layth ibn Sa‘d about the hadeeths which speak of the
divine attributes. All of them said: Accept them as they come, without
trying to interpret them. According to another report: Accept them as they
come without discussing how (and their nature). Narrated by al-Bayhaqi in
al-I‘tiqaad (p. 118). 

In the answers to questions no.
138920 and 178915 we
explained that the belief of Ahl as-Sunnah wa’l-Jamaa‘ah with regard to the
divine attributes is that they affirm them and they affirm their meanings on
the basis of what they really are and in the light of what is indicated by
the linguistic meaning of the word describing them; and they delegate to
Allah knowledge of how they are and their essence, whilst believing that
they cannot be understood as being indicative of any resemblance of the Lord
or any of His attributes to any created being. 

So we believe that the Most Merciful rose
over the Throne, and we believe that the Throne shook in a real sense at the
death of Sa‘d ibn Mu‘aadh (may Allah be pleased with him). In some reports
it says that that was because of the joy of the Lord, may He be exalted, as
referred to above. But we cannot ask how did the Most Merciful rise over the
Throne, just as we cannot ask how the Throne shook at the death of Sa‘d.
Rather we let it pass and we believe in it without asking how or trying to
interpret it or liken it to anything. 

Adh-Dhahabi (may Allah have mercy on him)
said: 

The Throne is a creation of Allah that is
subject to His control. If He wills that it should shake, it shakes by the
will of Allah. Allah instilled in it a sense of love for Sa‘d, just as He
instilled in Mount Uhud a sense of love for the Prophet (blessings and peace
of Allah be upon him). Allah, may He be exalted, says (interpretation of the
meaning): “O you mountains. Glorify (Allah) with him” [Saba’
34:10] and “The seven heavens and the earth
and all that is therein, glorify Him” [al-Isra’
17:44]. Then Allah included
all things in that and said: “and there is not a thing but glorifies His
Praise” [al-Isra’ 17:44].
And this is true. In Saheeh al-Bukhaari it is narrated that Ibn
Mas‘ood said: We used to hear the tasbeeh of the food as it was being eaten.
This is a broad topic and we have to believe in it.

Al-Baghawi (may Allah have mercy on him)
said: 

It is more appropriate to understand these
reports as they appear to be. The same applies to the words of the Prophet
(blessings and peace of Allah be upon him), “Uhud is a mountain that loves
us and we love it.” The shaking of that which is inanimate with the Prophets
and awliya’ (close friends of Allah) is not to be denied, as Uhud shook when
the Messenger of Allah (blessings and peace of Allah be upon him), Abu Bakr,
‘Umar and ‘Uthmaan were on it, and as the palm-trunk pillar shook with
sorrow when the Prophet (blessings and peace of Allah be upon him) left it
(and began to use the minbar instead).

End quote from Sharh as-Sunnah
(14/180-181) 

Shaykh al-Islam Ibn Taymiyah (may Allah
have mercy on him) said: 

The one who misinterprets that as meaning
that the bearers of the Throne rejoiced must produce evidence to support
what he says … even though the context and wording of the hadeeth are
contrary to this interpretation.

End quote from Majmoo‘ al-Fataawa
(6/554) 

Thirdly: 

The fact that the Throne shook at the
death of a created being does not suggest any imperfection on the part of
the Lord, may He be glorified; what shortcoming is there in that? Whether we
assume that the shaking was because of the joy of the Throne itself at the
coming of Sa‘d’s soul, and its appreciation of that, according to what some
of the scholars said,  or it was because of the joy of the Most Merciful,
may He be glorified and exalted, and His loving to meet His slave Sa‘d ibn
Mu‘aadh (may Allah be pleased with him), as it says in the hadeeth: “Whoever
loves to meet Allah, Allah loves to meet him, and whoever hates to meet
Allah, Allah hates to meet him.” 

Narrated by al-Bukhaari (6507) and Muslim
(2683) 

What imperfection can there be in the
Throne because of that, let alone attributing any kind of imperfection to
the Lord of the mighty Throne, may He be glorified and exalted?? 

The basic principle on which we must base
our words is the soundness or otherwise of the hadeeth. We have previously
stated that the hadeeth is sound beyond any shadow of a doubt, and that it
is mutawaatir (i.e., narrated by so many from so many that it is
inconceivable that they would all have agreed upon a lie) from the Messenger
of Allah (blessings and peace of Allah be upon him). Then we quoted the
views of the scholars concerning the way in which it is to be understood. 

The shaking of the Throne, the creaking of
the sky, and so on are not attributes of the Most Merciful, may He be
glorified and exalted, as we have pointed out; rather it is an attribute of
the Throne, which is something created. 

Ash-Dhahabi (may Allah have mercy on him)
said:

The creaking of the sky has nothing
whatsoever to do with the divine attributes; rather it is like the shaking
of the Throne at the death of Sa‘d, and like the cleaving asunder of the
heavens on the Day of Resurrection and so on.
