The time of the onset of the Hour is not known to anyone except Allah (may He be glorified and exalted). Nevertheless, He has ordained signs which will indicate that it is close at hand, so that the Muslim may be careful and strive to prepare for that momentous Day. In this hadith, the Prophet (blessings and peace of Allah be upon him) tells us that one of the signs of the approach of the Hour is that beneficial knowledge that is accompanied by righteous deeds will be taken away with the death of knowledgeable people, not by means of it being erased from people’s hearts. Then the people will follow ignorant leaders who will speak about religious issues on the basis of their own personal views, and they will issue fatwas that are based on ignorance. Thus ignorance will prevail and spread among the people, and that will result in people no longer having fear of Allah in their hearts. So a great deal of alcohol will be drunk, and it will become widespread among people despite the fact that it is forbidden. Allah (may He be exalted) says: {O you who have believed, indeed, intoxicants, gambling, [sacrificing on] stone altars [to other than Allah], and divining arrows are but defilement from the work of Satan, so avoid it that you may be successful } [al-Ma’idah 5:90]. The word khamr (intoxicants) comes from a root meaning to cover. It is so called because it covers the mind so that one cannot think properly, as a result of that the drinker falls into sins that lead to doom. Another sign of the approach of the Hour is that zina (unlawful sexual relationships) and shameful deeds will become widespread, as mentioned in the report of Muslim, and they will become very clearly prevalent, even though Allah has forbidden them, as He says: {And do not approach unlawful sexual intercourse} [al-Isra’ 17:32]. It is as if these things are singled out for mention because they indicate that matters are getting out of hand, which if they are brought under control, will be a cause of well-being in this world and the hereafter. The first is religion, because the taking away of knowledge will undermine religion. The second is reason, because it is undermined by consuming intoxicants. The third is lineage, because it is undermined by zina. The undermining of these three things indicates that the world is heading towards ruin. This hadith indicates that Allah (may He be exalted) has already decreed that the ruin of life on earth will come once mischief and corruption become prevalent and widespread. It also indicates that we are urged to acquire knowledge, for it will not be taken away except through the death of knowledgeable people. This hadith is one of the signs of the prophethood of the Prophet (blessings and peace of Allah be upon him). .
