It has been reported from ‘Ali, Ibn ‘Abbas, ‘Ubadah bin As-Samit, Abu Hurayrah, Shaddad bin Aws, Ibn ‘Umar, Muhammad bin ‘Ali bin Al-Husayn, Makhul, Bakr bin ‘Abdullah Al-Muzani, Bukayr bin Al-Ashaj, Malik, Ibn Abi Dhib, and ‘Abdul-‘Aziz bin Abi Salamah Al-Majishun, they all said, “Ash-Shafaq is the redness (in the sky).”

‘Abdur-Razzaq recorded from Abu Hurayrah that he said, “Ash-Shafaq is the whiteness. So Ash-Shafaq is the redness of the horizon, either before sunset, as Mujahid said or after sunset, as is well known with the scholars of the Arabic Language.

Al-Khalil bin Ahmad said, “Ash-Shafaq is the redness that appears from the setting of sun until the time of the last ‘Isha’ (when it is completely dark). When that redness goes away, it is said, ‘Ash-Shafaq has disappeared.’”

Al-Jawhari said, “Ash-Shafaq is the remaining light of the sun and its redness at the beginning of the night until it is close to actual nighttime (darkness).” Ikrimah made a similar statement when he said, “Ash-Shafaq is that what is between Al-Maghrib and Al-'Isha'”

In the Sahih of Muslim, it is recorded from ‘Abdullah bin ‘Amr that the Messenger of Allah said,

“The time of Al-Maghrib is as long as Ash-Shafaq has not disappeared.”

In all of this, there is a proof that Ash-Shafaq is as Al-Jawhari and Al-Khalil have said.

Ibn ‘Abbas, Mujahid, Al-Hasan and Qatadah, all said that,

{and what it Wasaqa} means “What it gathers.” Qatadah said, “The stars and animals it gathers.”
Ikrimah said,

“What it drives into due to its darkness, because when it is nighttime everything goes to its home.” Concerning Allah’s statement,

{And by the moon when it Ittasaqa.} Ibn ‘Abbas said, “When it comes together and becomes complete.” Al-Hasan said, “When it comes together and becomes full.”

Qatadah said, “When it completes its cycle.” These statements refer to its light when it is completed and becomes full, as the idea was initiated with “The night and what it gathers.” Allah said,

Al-Bukhari recorded from Mujahid that Ibn ‘Abbas said,

“Stage after stage. Your Prophet has said this.” Al-Bukhari recorded this statement with this wording.
‘Ikrimah said,

{From stage to stage.} “Stage after stage. Weaned after he was breast feeding, and an old man after he was a young man.” Al-Hasan Al-Basri said,

{From stage to stage.} “Stage after stage. Ease after difficulty, difficulty after ease, wealth after poverty, poverty after wealth, health after sickness, and sickness after health.”

The Disapproval of Their Lack of Faith, giving Them Tidings of the Torment, and that the Ultimate Pleasure will be for the Believers

Allah said,

meaning, what prevents them from believing in Allah, His Messenger and the Last Day, and what is wrong with them that when Allah’s Ayat and His Words are recited to them they do not prostrate due to awe, respect and reverence?
Concerning Allah’s statement,

{Nay, those who disbelieve deny.} meaning, from their mannerism is rejection, obstinacy, and opposition to the truth.

{And Allah knows best what they gather,} Mujahid and Qatadah both said, “What they conceal in their chests.”

meaning, ‘inform them, O Muhammad, that Allah has prepared for them a painful torment.’

Then Allah says,

This is a clear exception meaning, ‘but those who believe.’ This refers to those who believe in their hearts. Then the statement, “and do righteous good deeds,” is referring to that which they do with their limbs.

{for them is a reward} meaning, in the abode of the Hereafter.

{that will never come to an end.} Ibn ‘Abbas said, “Without being decreased.” Mujahid and Ad-Dahhak both said, “Without measure.” The result of their statements is that it (the reward) is without end. This is as Allah says,

{A gift without an end.} (11:108) As-Suddi said, “Some of them have said that this means without end and without decrease.”

This is the end of the Tafsir of Surat Al-Inshiqaq. All praise and thanks are due to Allah, and He is the giver of success and freedom from error.
