The gradualness of Qur'anic revelation is implied in the verbal form nazzalna.
The Qur-an was being revealed stage by stage as the occasion demanded and at the date of this Sura it was still one of the earlier stages. Persecution, abuse, and false charges were being levelled against the man of Allah, but he is bidden to stand firm and do his duty. In a minor degree this applies to all of us who suffer in the cause of Truth.
