Al-Baqarah 2:210

Do not delay embracing the Faith

هَلْ يَنظُرُونَ إِلاَّ أَن يَأْتِيَهُمُ اللَّهُ فِي ظُلَلٍ مِّنَ الْغَمَامِ وَالْمَلَـئِكَةُ

(Do they then wait for anything other than that Allah should come to them over the shadows of the clouds and the angels) on the Day of Resurrection to judge the early and the latter creations. Allah shall then reward each according to his or her deeds; and whoever does good shall see it, and whoever does evil shall see it. This is why Allah said:

وَقُضِىَ الأَمْرُ وَإِلَى اللَّهِ تُرْجَعُ الأُمُورُ

((Then) the case would be already judged. And to Allah return all matters (for decision).)

Similarly, Allah said:

كَلاَّ إِذَا دُكَّتِ الاٌّرْضُ دَكّاً دَكّاً - وَجَآءَ رَبُّكَ وَالْمَلَكُ صَفّاً صَفّاً - وَجِىءَ يَوْمَئِذٍ بِجَهَنَّمَ يَوْمَئِذٍ يَتَذَكَّرُ الإِنسَـنُ وَأَنَّى لَهُ الذِّكْرَى

(Nay! When the earth is ground to powder. And your Lord comes with the angels in rows. And Hell will be brought near that Day. On that Day will man remember, but how will that remembrance (then) avail him) (89:21-23) and:

هَلْ يَنظُرُونَ إِلاَ أَن تَأْتِيهُمُ الْمَلَـئِكَةُ أَوْ يَأْتِىَ رَبُّكَ أَوْ يَأْتِىَ بَعْضُ ءَايَـتِ رَبِّكَ

(Do they then wait for anything other than that the angels should come to them, or that your Lord (Allah) should come, or that some of the signs of your Lord should come (i. e., portents of the Hour, e.g., rising of the sun from the west)!) (6:158)

Abu Ja`far Razi reported that Abu Al-`Aliyah narrated that:

هَلْ يَنظُرُونَ إِلاَّ أَن يَأْتِيَهُمُ اللَّهُ فِي ظُلَلٍ مِّنَ الْغَمَامِ وَالْمَلَـئِكَةُ

(Do they then wait for anything other than that Allah should come to them over the shadows of the clouds and the angels) means, the angels will descend on the shadows of clouds, while Allah comes as He wills. Some of the reciters read it,

هَلْ يَنظُرُونَ إِلاَّ أَن يَأْتِيَهُمُ اللَّهُوَالْمَلَـئِكَةُفِي ظُلَلٍ مِّنَ الْغَمَامِ

Do they then wait for anything other than that Allah should come to them and also the angels over the shadows of the clouds. This is similar to Allah's other statement:

وَيَوْمَ تَشَقَّقُ السَّمَآءُ بِالْغَمَـمِ وَنُزِّلَ الْمَلَـئِكَةُ تَنزِيلاً

(And (remember) the Day when the heaven shall be rent asunder with clouds, and the angels will be sent down, with a grand descending.) (25:25)
