Hadith Commentary:
Vocabulary of the Hadith:
(1)
Nahr al-Hayat,
or al-Haya:
The river of life,
or the river of rain,
Rain is called "haya"
because it becomes the cause of the life and fertility of the earth,
In the same way, those who are washed with this water
will emerge fresh and lively, just as greenery emerges fresh and lively after rain.
(2)
Multawiyah:
From "iltawa",
meaning twisted or coiled.

Benefits and Issues:
(1)
Entry into Paradise
depends on the mercy of Allah, the Exalted.
It is as a result of His mercy that one is granted the ability to perform righteous deeds,
and if His mercy is present, then deeds will be accepted,
and as a result of His mercy, entry into Paradise will occur.
(2)
The people of faith,
who are evil-doers and undergo punishment for their sins, will enter Hell,
When the fire of Hell consumes their sins and they are burnt and turned to coal,
the effect of faith will remain in their hearts and they will even be able to see Paradise,
then, as a result of intercession, they will be taken out of Hell.
(3)
There is increase and decrease in faith; not everyone's faith is equal and identical.

Benefit:

“Recite, then, whatever is easy for you from the Qur’an.”
In this hadith, it is mentioned that the Messenger of Allah (sallallahu alayhi wa sallam) recited Surah Qaf in the Fajr prayer.
