Abu Dawud

Benefits and Issues:
In Tafsir Ruh al-Ma‘ani (14/158), it is mentioned that in the recitation of Ali (radi Allahu anhu), Ibn Mas‘ud (radi Allahu anhu), Ibn Wathab, and A‘mash, this word was recited with truncation (tarakhīm) as "Ya Mālu".

Hadith Commentary:
Malik is the guardian of Hell who is appointed over the Fire.
The inhabitants of Hell will repeatedly request him to ask his Lord to cause them to die.
He will reply to them that you will remain in it forever.

That is, the angel Malik will say to them:
The list of your crimes is very long and extensive, therefore a long period is required to punish you, so remove the thought of death from your minds.
You can only be punished by being kept alive, so you will have to remain here and you will indeed be kept alive.
Ibn Abbas (radi Allahu anhu) said:
The angel Malik, after hearing the cries and wailing of the inhabitants of Hell, will remain silent for a thousand years.
Then he will reply to them with just two words: you are to remain here.
(Tafsir Ibn Kathir: 4/160)

Hadith Commentary:
The complete verse is as follows: ﴿وَنَادَوْا يَا مَالِكُ لِيَقْضِ عَلَيْنَا رَبُّكَ قَالَ إِنَّكُمْ مَاكِثُونَ﴾ (Az-Zukhruf: 77)
That is, "The inhabitants of Hell will call out to the keeper of Hell, Malik, saying: 'Ask your Lord to put an end to us.' He will reply: 'Indeed, you are to remain (in this punishment).'”
From this, the existence of angels and their being assigned to various duties is also established.
In the recitation of Abdullah ibn Mas'ud (radi Allahu anhu), the word is "wa nadaaw ya Maal"—a shortened form of "ya Malik."
The meaning of both is the same: that the inhabitants of Hell will call out to the keeper of Hell, Malik.
From this as well, the existence of angels is established.

Hadith Commentary:
1.
The one who is called upon is referred to as the "munada."
Omitting the last letter of the munada is called "tarkheem."
After tarkheem, there are two possible grammatical cases for the munada:
Either its original vowel is made permanent, or the last letter is considered permanent and is read with the nominative case (raf‘).
Abdullah ibn Mas‘ud (radi Allahu anhu) recited the word "Malik" with tarkheem.
Now, there are three ways to recite this word:
➊
Ya Malik (with nominative case/raf‘)
Ya Mal (with genitive case/jarr)
➋
Ya Mal (with accusative case/nasb)
This difference is only in grammatical inflection; there is no change in meaning.
2.
It should be noted that Malik is the angel who is appointed as the general supervisor of Hell (Jahannam).
3.
Imam Bukhari (rahimahullah) has also established the existence of angels from this hadith.

Hadith Commentary:
➊
The inhabitants of Hell, utterly despondent due to the severity of the punishment and the absence of any reduction or respite, will call out to Malik, the angel appointed over Hell. They will say:
“O Malik! Neither has there been any decrease in our punishment, nor has there ever been any increase in its interval. So, ask your Lord to finish us off in one go and bring an end to this entire matter of punishment.”
Malik will reply:
“For the recompense of your crimes, a very long period is required; therefore, remove the thought of death from your minds.
You can be punished while remaining alive.
Thus, you will have to stay here, and you will have to endure the punishment while remaining alive.”

➋
In Jami‘ at-Tirmidhi, the statement of Imam A‘mash is transmitted that between the supplication and plea of the inhabitants of Hell and Malik’s response, there will be an interval of one thousand years.
(Jami‘ at-Tirmidhi, Description of Hell, Hadith: 2586)

English Commentary:
1:
Al-Zukhruf: 77 (“Malik” is the name of the keeper of Hell, whom the inhabitants of Hell will call upon and say: Ask your Lord to let us die so that we may be saved from the torment of Hell. The answer will be: Here you will remain forever.)
2:
It is narrated in Sahih Muslim that the Prophet (sallallahu alayhi wa sallam) used to recite the entire Surah Qaf during the Friday sermon (khutbah). This hadith proves that, as an admonition and reminder, one should recite some verse of the Qur’an.

Benefit:
Malik is the keeper of Hell; the inhabitants of Hell will repeatedly request him to ask your Lord to cause us to die. He will reply to them that you will remain therein forever. ()
