Sign of the Day of Judgment: The poor will become rich
عن أبى هريرة رضى الله عنه قال : كان النبى صلى الله عليه وسلم بارزا يوما للناس ، فأتاه رجل فقال : متى الساعة ؟ قال : ما المسئول عنها بأعلم من السائل ، وسأخبرك عن أشراطها : إذا ولدت الأمة ربتها وإذا تطاول رعاة الإبل البهم فى البنيان فى خمس لا يعلمهن إلا الله ثم تلا النبى صلى الله عليه وسلم :- إن الله عنده علم الساعة
Hazrat Abu Huraira (may Allah be pleased with him) narrates that one day the Prophet Muhammad (peace be upon him) was present among the people when suddenly a man came and asked: When will the Day of Judgment occur? The Prophet (peace be upon him) replied: The one asked does not know more than the one who asks, but I will tell you some signs of the Day of Judgment. When a slave woman gives birth to her master, and when unknown black shepherds of camels compete with each other in building sky-high buildings (then the Day of Judgment will be near). Indeed, the knowledge of the Day of Judgment is among five things known only to Allah Almighty. Then the Prophet (peace be upon him) recited this verse: Indeed, only Allah has knowledge of the Hour.

Benefits:
➊ The becoming wealthy and influential of poor, destitute, and destitute-like people is a sign of the nearness of the Day of Judgment.
➋ At one time, the Arabian region consisted of deserts and wastelands, and most of its inhabitants depended on livestock for their livelihood. But since Allah Almighty caused oil springs to flow in the deserts of Arabia, the Arabian deserts have turned into meadows and the wastelands into gardens, and everywhere prosperity and abundance of wealth are evident.
➌ Many people who appear to be beggars are, upon revelation of the truth, found to be playing with millions. Recently, it was reported in newspapers that in some border area, a beggar comes in a private car to beg, and begging is such a profitable business that there is no question of loss. Therefore, many cunning individuals are rapidly joining this profession. May Allah protect us from this curse. آمين
