The Prophet (May peace be upon him) used to seek refuge in Allah for al-Hasan and al-husain, saying ; I seek refuge for both of you in the perfect words of Allah from every devil and every poisonous thing and from the evil eye which influences. He would then say; your father sought refuge in Allah by them for Ismail and Ishaq. Abu Dawud said; this is a proof of the fact that the Quran is not created.
"When Allah, the exalted, speaks to send revelation, the inhabitants of heaven hear the clanging of a bell from the heavens like a chain being dragged across a rock, and they swoon. They continue to remain like that until Jibril comes to them. When he comes to them, they recover and say: 'O Jibril, what did your Lord say?' He would say: 'The truth,' and they would say: 'The truth, the truth.'"
The Messenger of Allah (ﷺ) said: When Allah created Paradise, He said to Gabriel: Go and look at it. He went and looked at it, then came and said: O my Lord! By Thy might, no one who hears of it will fail to enter it. He then surrounded it with disagreeable things, and said: Go and look at it, Gabriel. He went and looked at it, then came and said: O my Lord! By Thy might, I am afraid that no one will enter it. When Allah created Hell, He said: Go and look at it, Gabriel. He went and looked at it, then came and said: O my Lord! By Thy might, no one who hears of it will enter it. He then surrounded it with desirable things and said: Go and look at it, Gabriel. He went, looked at it, then came and said: O my Lord! By Thy might and power, I am afraid that no one will remain who does not enter it.
