The taking up of the Quran and its being taken away by night

Shaqiq bin Salamah said that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "How will you be when a night comes upon the Qur'an in which the Qur'an is taken away?" The narrator asked: "O Abu Abd al-Rahman, how can that be, when the Qur'an is preserved in the breasts of men?" He said: "Allah will send a pure wind, and every believer will die."

Shaddad bin Ma'qil said that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Indeed, this Qur'an which is among you is about to be taken away from you." The narrator said: I said: "How will it be taken from us, when we have preserved it in our hearts and recorded it in our copies?!" He said: "A night will pass over it in which what is preserved in the hearts will be taken away and what is recorded in the copies will be erased, and people will wake in the morning empty of it." Then he recited this verse: "And if We willed, We could take away all that We have revealed to you." [Al-Isra: 86]
