عَنْ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُما أَنَّ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَفَاتِحُ الغَيْبِ خَمْسٌ، {إِنَّ اللَّهَ عِنْدَهُ عِلْمُ السَّاعَةِ وَيُنْزِلُ الغَيْثَ وَيَعْلَمُ مَا فِي الأَرْحَامِ وَمَا تَدْرِي نَفْسٌ مَاذَا تَكْسِبُ غَدًا وَمَا تَدْرِي نَفْسٌ بِأَيِّ أَرْضٍ تَمُوتُ إِنَّ اللَّهَ عَلِيمٌ خَبِيرٌ}».
Na imepokelewa kutoka kwa bin Omari -radhi za Mwenyezi Mungu ziwe juu yake na baba yake -kwamba Mtume wa Mwenyezi Mungu -rehema na amani ziwe juu yake - amesema: "Funguo za mambo ya ghaibu ni tano, "Hakika kuijua Saa ya Kiyama kuko kwa Mwenyezi Mungu. Na Yeye ndiye anayeiteremsha mvua. Na anavijua vilivyo ndani ya matumbo ya uzazi. Na haijui nafsi yoyote itachuma nini kesho. Wala nafsi yoyote haijui itafia nchi gani. Hakika Mwenyezi Mungu ndiye Mwenye kujua, Mwenye habari".
Ibn ‘Umar (may Allah be pleased with him and his father) reported that the Messenger of Allah (ﷺ) said: "The keys of the unseen are five {Indeed, Allah has the knowledge of the Hour. He sends down the rain and knows what is in the wombs. No soul knows what it will do tomorrow, nor does any soul know in which land it will die. Indeed, Allah is All-Knowing, All-Aware.}"
