They will not be grieved by the greatest terror, and the angels (21:103)

Almuntakhab Fi Tafsir Alquran Alkarim

Nor shall they be disturbed, grieved nor shocked by the overwhelming terror -of The Day of Judgement- and they shall be received with a hearty welcome by the angels who put their minds at rest and say to them: this is the happy day you were promised

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(21:103) the time of the great fright will not trouble them at all; *98 the angels will rush forth to receive them, saying: "This is the very Day which you were promised!"

They will not be grieved by the greatest terror, and the angels meaning

*98) That is, "The time of mustering and going before Allah will be very dreadful for the common people but the righteous people will have full peace of mind because everything will be happening according to their expectations. Their faith and the righteous deeds they did in the world, will help console them by the grace of Allah and, instead of grief and sorrow, they will be filled with the hope that they are going to get their promised rewards."

وہ انتہائی گھبراہٹ کا وقت اُن کو ذرا پریشان نہ کرے گا، اور ملائکہ بڑھ کر اُن کو ہاتھوں ہاتھ لیں گے کہ "یہ تمہارا وہی دن ہے جس کا تم سے وعدہ کیا جاتا تھا"
