فَذَكِّرْ إِن نَّفَعَتِ الذِّكْرَى
So admonish, for admonition is indeed beneficial:
Agha Ali Puya Commentary
Commentary on Quran 87:9
[Pooya/Ali Commentary 87:9] The effectiveness of the admonition depends upon the capacity of those who hear the reminder. The cases where admonition produces positive benefits and where it does not, are mentioned in verses 10 and 11. When the message of Allah is proclaimed, it creates positive response in those in whose hearts is the fear of Allah, which those who run away from it, reject and belie it prepare their own ruin. They will be thrown into the fire of hell where they will neither die nor live. See commentary of Ta Ha: 74. Those in whose hearts is the fear of Allah purify their souls by not disobeying or revolting against the commands of Allah, and by submitting their souls to the will of Allah, and never going astray from the path of righteousness. They are those who really glorify the name of their most high Lord as mentioned in verse 1. The transgressors prefer the life of this world but those who have purified their souls know that the blessings of the hereafter are for ever with which they will be rewarded by Allah. Refer to the commentary of Ibrahim: 4. Godliness and righteousness have been preached to mankind in all ages. They have been renewed and reiterated again and again. All the prophets of Allah came to convey the message of Allah. Some paid attention and accepted the truth and some rejected and rebelled against it. There must have been some testament of Ibrahim, which like so many other scriptures is now lost to the world. A book, said to be apocryphal, entitled the Testament of Abraham was translated from the Greek original and published for the first time in 1892, at Cambridge, by M. R. James. The book of Musa referred to here is the original Tawrat. The present Pentateuch is a man-made revision (see page 374).
