Abu al-Aswad reported: Abu Mūsa al-Ash'ari sent for the reciters of the people of Basra. Three hundred men who had recited the Qur'an came to him. He said: "You are the best among the people of Basra and their reciters. So, recite it. And let not hope of a long life delude you, and thus your hearts would harden as the hearts of those before you had hardened. We used to recite a Surah, which we would liken to Barā‘ah in terms of length and toughness, and I was made to forget it. However, I memorized from it: "If the son of Adam had two valleys of wealth, he would seek a third valley, and nothing would fill the inside of the son of Adam except dust". We used to recite a Surah, which we would liken to one of the Musabbihāt, and I was made to forget it. However, I memorized from it: "O you who believe, why do you say what you do not do?" This will be written as a testimony on your necks, and you will be asked about it on the Day of Judgment..
Commentary :
The Prophet (may Allah's peace and blessings be upon him) used to direct his Companions and advise them to refrain from keenness on worldly life and hope for an extended stay in it. And the Companions (may Allah be pleased with them) did the same with the Tābi'is.
In this tradition, Abu al-Aswad ad-Dīli informs that Abu Mūsa al-Ash‘ari (may Allah be pleased with him) sent for the reciters among the people of Basra to come to him and gather there. Basra is a city located in the south of Iraq. "Three hundred men, who had recited the Qur'an" and memorized it "came to him." He advised and directed them, saying: You are the best among the people of Basra and you are the people of the Qur’an among them. Then, he instructed them to read the Qur’an and recite it in the most proper manner, which entails understanding its meanings, reflecting upon its verses, and acting upon its rulings. And he said to them: "And let not hope of a long life delude you and thus your hearts would harden," i.e., do not have high hopes for worldly life and do not wish to stay therein for long, as this corrupts the hearts by dragging them to greed and hardness, and thus they will not soften to Dhikr or derive benefit from admonition or rebuke. As a result, you will have such hardness and aversion within your hearts that had befallen the nations before you due to their hopes for an extended stay in the life of this world. This includes a reference to the verse that reads: {Has the time not yet come for those who believe that their hearts should be humbled at the remembrance of Allah and the truth that has been revealed? They should not be like those who were given the Scriptures before, whose hearts grew hard after the passage after a long period of time, and many of them were evildoers.} [Surat al-Hadīd: 16]
Then, he informed that they used to recite a long Surah of the Qur’an, whose recitation was abrogated, and they would liken it to Surat Barā’ah, which is Surat at-Tawbah, in terms of length and toughness. He further said that he was made to forget it. Then, Abu Mūsa (may Allah be pleased with him) made an exception and informed that he memorized from the meanings of this Surah such words that contain dispraise of attention on worldly life and the love and desire for having a lot of it. He said: "If the son of Adam had two valleys of wealth, he would seek a third valley." A valley is any gap between mountains or hills. "and nothing would fill the inside of the son of Adam except dust", i.e., he continues to be keen on worldly life till he dies, and his inside gets filled with the dust of his grave. The inside may also be intended to refer to the heart, and the meaning is that he does not get bored of the love for wealth. This is because man is naturally inclined to love wealth and has an unquenchable greed for it, and he has no limit to stop except a matter like his own, namely dust.
Then, Abu Mūsa (may Allah be pleased with him) informed that they used to recite a Surah which they would liken to one of the Musabbihāt, which are the Surahs that begin with "subhān, sabbaha, yusabbihu, sabbih ism rabbika" (glory be to, glorified, glorifies, glorify the name of your Lord), and that he was made to forget it; and he memorized from it: "O you who believe, why do you say what you do not do?" This is a question that signifies disapproval and rebuke for those who attribute to themselves good things that they do not do, either in relation to the past, in which case they would be liars, or concerning the future, and this would be a contradiction; both are dispraised. "This will be written as a testimony on your necks and you will be asked about this on the Day of Judgment" i.e., these false statements will be recorded against you, for what you said and did not do is a testimony from you, and you are liable for it, and you will be held accountable, and it will entail an evil recompense on the Day of Judgment.
This abrogation, which Abu Mūsa (may Allah be pleased with him) told about in this Hadīth, is one of the abrogation types: the abrogation of words and recitation. Abrogation is of three types: First: Abrogation of rulings, while words and recitation endure. Second: Its opposite; and that is the abrogation of words and recitation, while the ruling endures. Third: Abrogation of the ruling along with the words and recitation. This is the abrogation which Allah Almighty mentions in the verse that reads: {We do not abrogate a verse or cause it to be forgotten.} [Surat al-Baqarah: 106] And also in the verses that read: {We will teach you [the Qur’an], so you will not forget*, except what Allah wills.} [Surat al-A‘la: 6-7] These two Surahs are among the Surahs Allah Almighty willed to be forgotten after He revealed them. This is because Allah Almighty does whatever He wills and is Able to do all things He wishes. Indeed, this is all possible. Let not one wrongly assume, because of this and the like of it, that any part of the Qur’an was lost. In fact, this is untrue, as established by the verse that reads: {It is We Who have sent down the Reminder, and it is We Who will preserve it.} [Surat al-Hijr: 9] This is also established by the consensus among the Companions and those after them that the Qur’an, which we are required to recite and act upon its rulings as a form of worship, is the text contained between the two covers of the Mus'haf, without addition or omission.
The Hadīth shows keenness to present advice to the Muslim reciters.
It contains dispraise of the keenness on worldly life and the hope for a long stay therein.
It includes dispraise of lying and bragging about something one did not do.
The Hadīth also mentions that a person's speech is recorded and he will be asked about it on the Day of Judgment.
And it indicates that a believer should be chiefly concerned about working for the Hereafter and he should not be deceived by worldly life and its desires..
