19ثُمَّ إِنَّ عَلَينا بَيانَهُAli UnalThereafter, it is for Us to explain it.1The last four verses seem to have no relation with those before or after them. They are concerned with the revelation of the Qur’ān to God’s Messenger, upon him be peace and blessings, and his manner of receiving it. The Messenger, upon him be peace and blessings, showed great concern in receiving and committing to heart the Qur’ān during its revelation; and, therefore, he tried to repeat and memorize it. He was also very concerned about fully understanding the meaning. These verses, like 20: 114, which is almost of the same import, assure him that God will enable him to memorize it and understand its meaning. As for the reason why these verses exist between the verses concerning the Day of Resurrection, the Messenger, upon him be peace and blessings, may have shown special care in memorizing them during their revelation.
