سُوْرَةُ الْحِجْرِ

Surah Al-Hijr (15) — Ayah 2

The Rock · Meccan · Juz 14 · Page 262

رُّبَمَا يَوَدُّ ٱلَّذِينَ كَفَرُوا۟ لَوْ كَانُوا۟ مُسْلِمِينَ ﴿2﴾
How much would those who disbelieved wish that they had been Muslims [those who have submitted themselves to Allâh’s Will in Islâm i.e. Islâmic Monotheism - this will be on the Day of Resurrection when they will see the disbelievers going to Hell and the Muslims going to Paradise].
رُّبَمَا rubamā Perhaps
يَوَدُّ yawaddu will wish
ٱلَّذِينَ alladhīna those who
كَفَرُوا۟ kafarū disbelieved
لَوْ law if
كَانُوا۟ kānū they had been
مُسْلِمِينَ mus'limīna Muslims

2. A time [2] will come when the disbelievers will wish that they had been Muslims.

At Which Times Will the Disbelievers Wish They Had Been Muslims?
"Rubama" is used for both abundance and scarcity, meaning it can signify "often" or "sometimes." This word is especially used in situations where it is expected that someone would remember frequently or all the time, but they do not, so it is said, "At least sometimes you will remember us." It can refer to any time when a disbeliever feels regret and remorse over his past life and deeds, and sees Muslims being honored and granted success and well-being in comparison. For example, at the Battle of Badr, the disbelievers were severely defeated and the Muslims were granted honor and victory, and such occasions can be numerous—both in this world and the Hereafter, even at the time of death. When the angels come in terrifying forms to take the soul of the disbeliever, and the final occasion for such a wish will be when, on the Day of Resurrection, the disbelievers see some sinful Muslims with them in Hell and say, "You are with us in Hell, so what benefit did your faith and monotheism give you?" At this, Allah will not allow any monotheist to remain in Hell. Upon saying this, the Messenger of Allah ﷺ recited this very verse, indicating that this will be the last occasion when the disbelievers will wish to have been Muslims.
