1. Here, the word duha has been used in contrast to the night; therefore, it implies the bright hours of the day. A precedent of it are(verses 97-98 of Surah Al-Aaraf), which say: Do the people of the settlements now feel secure that Our punishment will not come to them all of a sudden at night, while they might be fast asleep? Or, do they feel secure that Our punishment will not smite them all of a sudden during the day while they might be engaged in pastimes?” In these verses also since the word duha has been used in contrast to the night, it implies the day and not just forenoon.
وَالَّيۡلِ اِذَا سَجٰىۙ
(93:2) and by the night when it covers the world with peace:2
2. The word saja in the original does not only signify the spreading of darkness but it also contains the meaning of stillness and peace that prevails at night. This quality of night deeply relates to the theme that follows.
مَا وَدَّعَكَ رَبُّكَ وَمَا قَلٰىؕ
(93:3) (O Prophet), your Lord has neither forsaken you, nor is He displeased.3
3. Traditions show that revelations to the Prophet (peace be upon him) had remained suspended for some period of time. Different traditions have mentioned different durations of this period. Ibn Juraij has mentioned it to be 12 days, Kalbi 15 days, Ibn Abbas 25 days, and Suddi and Muqatil have stated that it extended to 40 days. In any case the period was so long that it made the Prophet (peace be upon him) sorrowful, and the opponents also had the opportunity to taunt him.
For whenever a new Surah came down, the Prophet (peace be upon him) would recite it before the people. Therefore, when he did not recite any new revelation to them for quite some days, the opponents thought that the fountainhead from where the revelation came, had dried up. Jundub bin Abdullah al-Bajali has related that when Angel Gabriel stopped coming,
the pagans started saying that Muhammad (peace be upon him) had been forsaken by his Lord. (Ibn Jarir, Tabarani, Abd bin Humaid, Saeed bin Mansur, Ibn Marduyah). Other traditions show that Umm Jamil, wife of Abu Lahab, who was an aunt of the Prophet (peace be upon him) and whose house adjoined his, said to him: It appears your satan has forsaken you.
Aufi and Ibn Jarir have related, on the authority of Ibn Abbas, that when Gabriel did not visit him for several days, the Prophet (peace be upon him) became anxious and distressed, and the pagans began to say that his Lord had become angry with him and had forsaken him. In the mursal traditions of Qatadah and Dahhak almost the same theme has been expressed.
The Prophet’s (peace be upon him) extreme grief and anguish in this condition has also been referred to in several traditions. And this was natural. The apparent indifference on the part of the beloved, the apparent deprivation of the contact with the source of power, which was his chief support, in the soul-destroying conflict between belief and unbelief,
and above all, the taunts and jeers of the enemy, when all these things combined they must have caused great anguish to the Prophet (peace be upon him), and he must be thinking that because of some error that he might have committed, his Lord had become displeased with him and had forsaken and left him to fight the battle between truth and falsehood alone.
