وَلِيُمَحِّصَ اللَّهُ الَّذِينَ آمَنُوا وَيَمْحَقَ الْكَافِرِينَ ﴿۱۴۱﴾ أَمْ حَسِبْتُمْ أَنْ تَدْخُلُوا الْجَنَّةَ وَلَمَّا يَعْلَمِ اللَّهُ الَّذِينَ جَاهَدُوا مِنْكُمْ وَيَعْلَمَ الصَّابِرِينَ ﴿۱۴۲﴾ وَلَقَدْ كُنْتُمْ تَمَنَّوْنَ الْمَوْتَ مِنْ قَبْلِ أَنْ تَلْقَوْهُ فَقَدْ رَأَيْتُمُوهُ وَأَنْتُمْ تَنْظُرُونَ ﴿۱۴۳﴾ وَمَا مُحَمَّدٌ إِلَّا رَسُولٌ قَدْ خَلَتْ مِنْ قَبْلِهِ الرُّسُلُ أَفَإِنْ مَاتَ أَوْ قُتِلَ انْقَلَبْتُمْ عَلَى أَعْقَابِكُمْ وَمَنْ يَنْقَلِبْ عَلَى عَقِبَيْهِ فَلَنْ يَضُرَّ اللَّهَ شَيْئًا وَسَيَجْزِي اللَّهُ الشَّاكِرِينَ ﴿۱۴۴﴾

﴾141﴿ And so that Allah may purify the believers and eliminate the disbelievers.
﴾142﴿ Do you think that you will enter Paradise while Allah has not yet made evident those among you who strive and has not yet made evident the patient ones
﴾143﴿ And indeed you used to long for martyrdom before you encountered it—then surely you have seen it with your own eyes while you were looking on.
﴾144﴿ And Muhammad, may Allah bless him and grant him peace, is no more than a messenger. Messengers have passed before him. So, if he dies or is killed, will you turn back on your heels? And whoever turns back on his heels will never harm Allah in any way, and Allah will soon reward the grateful.

[141] In this verse, other wisdoms are mentioned. (وَلِيُمَحِّصَ) – means to cleanse from impurities and to purify thoroughly.
[142] In this, another wisdom is mentioned. (أَمْ حَسِبْتُمْ) – the intended meaning of entering Paradise here is the initial entry. That is, did you think that without striving (jihad) and patience, you could attain the first entry into Paradise? This assumption is incorrect.
[143] In this, another wisdom is mentioned: you had desired the death of martyrdom after the Battle of Badr, so Allah granted you this wish at Uhud. (تَمَنَّوْنَ الْمَوْتَ) – here, "death" means martyrdom, because merely wishing for death is prohibited in the hadith, while hoping for martyrdom carries reward.
[144] In this verse, there is a warning for the believers: do not act relying solely on your leader, but place your trust in Allah, because even if the leader is a Prophet, death will come to him; but for Allah, there is never death or annihilation. This verse also teaches another good quality to prevent defeat. Abu Bakr (may Allah be pleased with him) recited this verse to affirm the death of the Prophet (may Allah bless him and grant him peace) (as mentioned in Sahih Bukhari). (وَمَا مُحَمَّدٌ إِلَّا رَسُولٌ) – This is a form of exclusive description: Muhammad (may Allah bless him and grant him peace) is not God to be protected from death; rather, his most important attribute is messengership, and messengership does not contradict mortality. (قَدْ خَلَتْ) – this refers to the passing of previous messengers, whether through death (like most Prophets), or the passage of their time without death (like ‘Isa, peace be upon him, whose continued life until near the Day of Judgment is established by authentic traditions). (الشَّاكِرِينَ) – here, it means those who remained steadfast at the passing of the Prophet (may Allah bless him and grant him peace), like Abu Bakr al-Siddiq (may Allah be pleased with him).
