Tafsir Ibn Kathir- Surah 1. Al-Fathiha, Ayah 4
ﻣَﺎﻟِﻚِ ﻳَﻮْﻡِ ﺍﻟﺪِّﻳﻦِ ٤ 4. 
The Owner of the Day of Recompense. Indicating Sovereignty on the Day of Judgment Allah mentioned His sovereignty of the Day of
Resurrection, but this does not negate His
sovereignty over all other things. For Allah mentioned
that He is the Lord of existence, including this earthly
life and the Hereafter. Allah only mentioned the Day of
Recompense here because on that Day, no one except Him will be able to claim ownership of anything
whatsoever. On that Day, no one will be allowed to
speak without His permission. Similarly, Allah said,

﴿ﻳَﻮْﻡَ ﻳَﻘُﻮﻡُ ﺍﻟﺮُّﻭﺡُ ﻭَﺍﻟْﻤَﻠَـﺌِﻜَﺔُ ﺻَﻔّﺎً ﻻَّ ﻳَﺘَﻜَﻠَّﻤُﻮﻥَ ﺇِﻻَّ ﻣَﻦْ ﺃَﺫِﻥَ ﻟَﻪُ ﺍﻟﺮَّﺣْﻤَـﻦُ ﻭَﻗَﺎﻝَ ﺻَﻮَﺍﺑﺎً ﴾

(The Day that Ar-Ruh (Jibril (Gabriel) or another angel)
and the angels will stand forth in rows, they will not
speak except him whom the Most Gracious (Allah)
allows, and he will speak what is right.) (78:38),

﴿ﻭَﺧَﺸَﻌَﺖِ ﺍﻷَﺻْﻮَﺍﺕُ ﻟِﻠﺮَّﺣْﻤَـﻦِ ﻓَﻼَ ﺗَﺴْﻤَﻊُ ﺇِﻻَّ ﻫَﻤْﺴﺎً﴾
(And all voices will be humbled for the Most Gracious
(Allah), and nothing shall you hear but the low voice of
their footsteps.)(20:108)

The Meaning of Yawm Ad-Din
Ibn `Abbas said, "Yawm Ad-Din is the Day of
Recompense for the creatures, meaning the Day of
Judgment. On that Day, Allah will reckon the creation
for their deeds, evil for evil, good for good, except for
those whom He pardons.'' In addition, several other
Companions, Tabi`in and scholars of the Salaf, said similarly, for this meaning is apparent and clear from
the Ayah.
