`Abdullah ibn `Umar (RA) narrated that: The Prophet (ﷺ) said, “The keys of the Unseen are five.” And then he recited this ayah from Surah Luqman, Chapter 31: Verse 34 ‘The knowledge of the hour of doom is certainly with Allah. And He sends down the rain. And He knows that which is in the wombs. And no person knows what he will earn tomorrow (in future). And no person knows in what (part of) the earth he will die. Allah is certainly Knowing, Informed.’

Zayd ibn Thabit (RA) said: I heard the Messenger of Allah (ﷺ) say: May Allah brighten a man who hears a tradition (meaning Hadith) from us, gets it by heart and passes it on to others. Many a
bearer of knowledge conveys it to one who is more well-versed than he is; and many a bearer of knowledge is not well-versed in it.

`Abdullah ibn `Amr (RA) said: I heard the Prophet (ﷺ) saying, “Allah will not deprive you of knowledge after he has given it to you, but it will be taken away through the death of the religious learned men with their knowledge. Then there will remain ignorant people who, when consulted, will give verdicts according to their opinions whereby they will mislead others and go astray.”
