It is narrated from Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him), he says: Your Prophet was given the keys to everything except five things. These five things are: {إِنَّ اللّٰہَ عِنْدَہُ عِلْمُ السَّاعَۃِ وَیُنَزِّلُ الْغَیْثَ وَیَعْلَمُ مَا فِی الْأَرْحَامِ وَمَا تَدْرِی نَفْسٌ مَاذَا تَکْسِبُ غَدًا وَمَا تَدْرِی نَفْسٌ بِأَیِّ أَرْضٍ تَمُوتُ، إِنَّ اللّٰہَ عَلِیمٌ خَبِیرٌ} … Knowledge of the Hour is with Allah alone, He sends down the rain, He knows what is in the wombs, no soul knows what it will earn tomorrow, and no person knows in which land he will die. Allah is All-Knowing, All-Aware. (Surah Luqman: 24) Amr bin Murrah says: I asked my teacher Abdullah bin Salamah whether he had heard this hadith directly from Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him)? He said: Yes, I have heard it more than fifty times.
