﴿ تَعْرُجُ ٱلْمَلَٰٓئِكَةُ وَٱلرُّوحُ إِلَيْهِ فِى يَوْمٍۢ كَانَ مِقْدَارُهُۥ خَمْسِينَ أَلْفَ سَنَةٍۢ ﴾

“all the angels and all the inspiration [ever granted to man] ascend unto Him [daily,] in a day the length whereof is [like] fifty thousand years…”

To Him to the place in the heaven to which His command descends ascend read feminine person ta‘ruju or masculine person ya‘ruju the angels and the Spirit Gabriel in a day fī yawmin is semantically connected to an omitted clause that is to say ‘in a day in which the chastisement befalls them’ on the Day of Resurrection whose span is fifty thousand years from the perspective of the disbeliever on account of the calamities he will encounter in it — but as for the believer it the mentioned day will be easier for him than an obligatory prayer which he performs in this world as stated in hadīth.
