"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.'" (Using translation from Abū Dāʾūd 4738)
"إذا تكَّلم اللهُ بالوحِى سَمِعَ أهلُ السَّماءِ الدُّنيا صْلصلةً كَجَرِّ السِّلسلِة على الصفا فَيَصعْقُون فلا يزالون كذلك حتى يأتيُهم جبْريلُ، حتَّى إذا جاءهم جبريلُ فُزّعَ عنْ قلوبهم فيقولون: يا جبريلُ ماذا قال رَبُّك؟ فيقولُ: ألحقّ: فيقولون: الْحقَّ الْحقَّ ".
