کیا اللہ کے رسول قتل ہو سکتے ہیں؟

The word ‘rusul’/’rasool’, in the Aaayat you’ve cited, is used in its plain literal meaning of a messenger and not as a term. The word ‘الّرُسُل‘ (Al-Rusul) is a plural of ‘الّرَسُوْل‘ (Al-Rasul). As pointed out by Ghamidi, the word has two connotations: one as a common Arabic word and the other as a term having a specific meaning. As a common Arabic word, it means a ‘messenger’ (one who delivers a message). So the Rusul of the Almighty can be His angels and His Prophets since both bear His message.

Here are some usages of Rusul in the Quran as a common Arabic word signifying angels and prophets:

i. Signifying Angels:

إِنَّهُ لَقَوْلُ رَسُولٍ كَرِيمٍ (١٩:١٨)

This is the word of a gracious and mighty messenger. (81:19)

الْحَمْدُ لِلَّهِ فَاطِرِ السَّمَاوَاتِ وَالْأَرْضِ جَاعِلِ الْمَلَائِكَةِ رُسُلًا أُولِي أَجْنِحَةٍ مَّثْنَى وَثُلَاثَ وَرُبَاعَ (١:٣٥)

Praise be to God, Creator of the heavens and the earth! He sends forth the angels as His messengers, with two, three or four pairs of wings. (35:1)

اللَّهُ يَصْطَفِي مِنَ الْمَلَائِكَةِ رُسُلًا وَمِنَ النَّاسِ إِنَّ اللَّهَ سَمِيعٌ بَصِيرٌ (٧٥:٢٢)

God chooses messengers from the angels and from men. Indeed, God hears all and observes all. (22:75)

ii. Signifying Prophets:

آمَنَ الرَّسُولُ بِمَا أُنزِلَ إِلَيْهِ مِن رَّبِّهِ وَالْمُؤْمِنُونَ كُلٌّ آمَنَ بِاللّهِ وَمَلآئِكَتِهِ وَكُتُبِهِ وَرُسُلِهِ (٢٨٥:٢)

The Messenger believes in what has been revealed to him by his Lord, and so do the faithful. They all believe in God and His angels, His scriptures, and His Prophets. (2:285)

Here the word Rusul is used to mean all prophets.

يَا مَعْشَرَ الْجِنِّ وَالإِنسِ أَلَمْ يَأْتِكُمْ رُسُلٌ مِّنكُمْ يَقُصُّونَ عَلَيْكُمْ آيَاتِي وَيُنذِرُونَكُمْ لِقَاء يَوْمِكُمْ (١٣٠:٦)

Then He will say: ‘Jinn and men! Did there not come to you Prophets of your own who proclaimed to you My revelations and warned you of this day?‘ (6:130)

Here also the word rusul is used on its literal meaning and signifies all prophets.

يَا بَنِي آدَمَ إِمَّا يَأْتِيَنَّكُمْ رُسُلٌ مِّنكُمْ يَقُصُّونَ عَلَيْكُمْ آيَاتِي فَمَنِ اتَّقَى وَأَصْلَحَ فَلاَ خَوْفٌ عَلَيْهِمْ وَلاَ هُمْ يَحْزَنُونَ (٣٥:٧)

Children of Adam, when Prophets of your own come to proclaim to you My revelations, those that take warning and mend their ways will have nothing to fear or to regret. (7:35)

Here also the same usage as above.

As a term of the Quran, the word Rasul signifies a cadre among the Prophets (Anbiya) of Allah. The difference between a Prophet (Nabi) and a Rasul is that the latter decides the fate of his nation in this world. The righteous are rewarded and wrong doers punished. The Quran says:

إِنَّ الَّذِينَ يُحَادُّونَ اللَّهَ وَرَسُولَهُ أُوْلَئِكَ فِي الأَذَلِّينَ كَتَبَ اللَّهُ لَأَغْلِبَنَّ أَنَا وَرُسُلِي إِنَّ اللَّهَ قَوِيٌّ عَزِيزٌ (٥٨ :٢٠-١)

Indeed, those who show hostility to Allah and His Rasul are bound to be humiliated. The Almighty has ordained that I and my Rusul shall always triumph. (58:20-21)

It is common knowledge that as a term the only Rasool that was raised among the Bani Israel was Moses (As) and after him it was only Jesus (as). Between these two, all the people raised by God were Prophets and it was among these that some were rejected or killed by the Israelites.

Also, it is not Ustaz Ghamidi’s position that a Rasool cannot be killed. A Rasool can be killed but not before Itmaam al Hujjah, which then necessitates that Divine punishment befalls those who rejected the Rasool. In other words, after Itmaam al-Hujjah, a Rasool can be killed, but eventually the plan of God will prevail and the disbeliever will be destroyed.

Please also see this verse, I think this is very critical in putting things in their right perspective.

وَ اِنۡ مَّا نُرِیَنَّکَ بَعۡضَ الَّذِیۡ نَعِدُہُمۡ اَوۡ نَتَوَفَّیَنَّکَ فَاِنَّمَا عَلَیۡکَ الۡبَلٰغُ وَ عَلَیۡنَا الۡحِسَابُ

We shall show you some part of the warning We are sounding them or give you death and after that deal with them Ourselves. Nonetheless, your responsibility is only to communicate and taking account is Our responsibility. (13:40)
