Harith al-A'war said: I entered the mosque and saw that people were engaging in idle talk, so I went to Sayyiduna Ali (may Allah be pleased with him) and said: Do you not see that people are sitting in the mosque making idle talk? He said: Are they really doing that? I said: Yes. Sayyiduna Ali (may Allah be pleased with him) said: Listen! I heard the Messenger of Allah (peace and blessings be upon him) say: "Soon there will appear tribulations." I asked: What is the way out of them? He (peace and blessings be upon him) said: "The Book of Allah (that is, the means of protection from them is the Qur'an). In Allah's Book is the news of those before you, and the news of those who will come after you, and it is the judge between you (that is, it is the ruling for the disputes among you). It is decisive, not jest. Whoever abandons it out of contempt, Allah will break him, and whoever seeks guidance in anything other than it, Allah will misguide him. It is the strong rope of Allah, and it is the wise reminder, and the straight path. It is a Book which desires (whims) cannot distort, and tongues cannot confuse, and the scholars never tire of it, nor does it become old from repeated recitation, and its wonders never end. It is a Book that when the jinn heard it, they could not help but say: 'Indeed, we have heard a marvelous Qur'an.' [الجن 1/72] Whoever speaks according to it has spoken the truth, whoever judges by it has judged justly, whoever acts upon it will be rewarded, and whoever calls to it is guided to the straight path." O Harith al-A'war, memorize it.
