It is derived from the very first cord "WatTur-i."
Period of Revelation
From the internal evidence of the subject matter it appears that thisSurah too was revealed in the same stage of the Holy Prophet's life atMakkah in which the Surah Adh-Dhariyat was revealed. While going throughit one can clearly feel that during the period of its revelation theHoly Prophet (peace and blessings of Allah be upon him) was beingshowered with objections and accusations but there is no evidence yetto show that severe persecution of the Muslims had started.
Subject Matter and Topics
The subject matter of its first section (vv. 1-28) is the Hereafter.As arguments for its possibility, necessity and occurrence had alreadybeen given in Surah Adh-Dhariyat, these have not been repeated here.However, swearing an oath by some realities and signs which testify tothe Hereafter, it has been stated most emphatically that it willsurely come to pass, and none has the power to prevent its occurrence.Then, it has been stated as to what will be the fate of those who denyit when it actually occurs, and how will those who believe in it andadopt the way of piety and righteousness accordingly, be blessed byAllah.
Then, in the second section (vv. 29-49) the Quraish chiefs' attitude towards the message of the Holy Prophet (peace andblessings of Allah he upon him) has been criticized. They called him asorcerer, a madman, or a poet, and would thus mislead the commonpeople against him so that they should not pay any serious attentionto the message he preached. They looked upon him as a calamity thathad suddenly descended on them and would openly wish that he met witha disaster so that they were rid of him. They accused him offabricating the Qur'an by himself and of presenting it in the name ofAllah, and this was, God forbid, a fraud that he was practising. Theywould often taunt him, saying that God could not have appointed anordinary man like him to the office of Prophethood. They expressedgreat disgust at his invitation and message and would avoid him as ifhe was asking them for a reward for it. They would sit and takecounsels together to devise schemes in order to put an end to hismission. And while they did all this they never realized what creedsof ignorance they were involved in and how selflessly and sincerelywas Muhammad (peace and blessings of Allah be upon him) exertinghimself to deliver them from their error. While criticizing them forthis attitude and conduct, Allah has put them certain questions, oneafter the other, each of which is either an answer to some objectionof theirs, or a criticism of some error. Then, it has been said thatit would absolutely be of no avail to show them a miracle in order toconvince them of his Prophethood, for they were such stubborn peopleas would misinterpret anything they were shown only to avoid affirmingthe faith.
In the beginning of this section as well as in its end, theHoly Prophet (peace and blessings of Allah be upon him) has been giventhe instruction that he should persistently continue giving hisinvitation and preaching his message in spite of the accusations andobjections of his opponents and enemies, and should endure theirresistance patiently till Allah's judgment comes to pass. Besides, hehas been consoled, as if to say "Your Lord has not left you alone toface your enemies, after raising you as a Prophet, but He isconstantly watching over you. Therefore, endure every hardshippatiently till the Hour of His judgment comes, and seek throughpraising and glorifying your Lord the power that is required forexerting in the cause of Allah under such conditions.
