In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Allaah [The Most High] informed us about the meeting between his two noble Prophets – Musa and Khidr [peace be upon them]: [قَالَ لَهُ ۥ مُوسَىٰ هَلۡ أَتَّبِعُكَ عَلَىٰٓ أَن تُعَلِّمَنِ مِمَّا عُلِّمۡتَ رُشۡدً۬ا – Musa (Moses) said to him (Khidr): May I follow you so that you teach me something of that knowledge (guidance and true path) which you have been taught (by Allah)?] [قَالَ إِنَّكَ لَن تَسۡتَطِيعَ مَعِىَ صَبۡرً۬ا – He (Khidr) said: Verily! You will not be able to have patience with me! “And how can you have patience about a thing which you know not? وَكَيۡفَ تَصۡبِرُ عَلَىٰ مَا لَمۡ تُحِطۡ بِهِۦ خُبۡرً۬ا – And how can you have patience about a thing which you know not?] [Surah Al-Kahf. Verses 66-68]

The first affair we would like to acquaint Mr Jurgen klopp with is one of the beautiful statements of Imaam As-Sadi [may Allaah have mercy upon him] regarding the verse: [وَكَيۡفَ تَصۡبِرُ عَلَىٰ مَا لَمۡ تُحِطۡ بِهِۦ خُبۡرً۬ا – And how can you have patience about a thing which you know not?] – That “From this is a command to employ careful deliberation and sound verification, and not rushing to pass judgement on a matter until what is intended by it is known and what its goal is”. (1)

The second affair we would like to acquaint Mr Jurgen Klopp with is the principle: “Al-Hukmu Alaa Shay’in Far’un An Tasawwurihee – Passing a judgement on something is to be (firmly linked and based) on understanding the affair”. Imaam Muhammad Ibn Saaleh Al-Uthaymeen [may Allaah have mercy upon him] said, “You do not pass a judgement on a thing except after being completely acquainted with it, so that the judgement is in accordance with what the real state of affairs is. And if this is not done, then great error occurs”. (2)

The third affair we would like to acquaint Mr Jurgen Klopp with is that comparing those who choose not to get vaccinated to drink drivers is a false and repugnant analogy! The consumption of alcohol – whether driving or not – is forbidden and one is commanded by the Creator to abandon everything that intoxicates the mind and intellect, whereas accepting a specific medication is recommended. Therefore, we suffice with the information on this link provided by Shaikh Abu Khadeejah [may Allaah preserve him]: https://www.abukhadeejah.com/taking-medicine-is-recommended-in-islam-for-the-one-who-is-sickbut-it-is-not-obligatory/

Finally, as for Mr Klopp’s fear-mongering about contagion, ignoring the experts and endangering others, then indeed all he did was propagate the false Aqeedah and superstitions of the pre-Islamic Arabs, as the saying goes: [لِكُلِّ قَوْمٍ وَارِث وَلِكُلِّ أَرْضٍ حَارِث وَلِكُلِّ ضَرٍّ هَالِك -Every people have their inheritors, every land has a cultivator and every evil has one destroyed by it]. Therefore, we suffice with the clarifications on the following links by Shaikh Abu Iyaadh and Shaikh Abu Khadeejah [may Allaah preserve them].

We ask Allaah to guide Jurgen Klopp and his ilk to the sound Aqeedah and protect us from the fear-mongers Aameen. And we ask Allaah, saying:

اللَّهُمَّ بِعِلْمِكَ الْغَيْبَ وَقُدْرَتِكَ عَلَى الْخَلْقِ أَحْيِنِي مَا عَلِمْتَ الْحَيَاةَ خَيْراً لِي وَتَوَفَّنِي إِذَا عَلِمْتَ الْوَفَاةَ خَيْراً لِي، اللَّهُمَّ إِنِّي أَسْأَلُكَ خَشْيَتَكَ فِي الْغَيْبِ وَالشَّهَادَةِ، وَأَسْأَلُكَ كَلِمَةَ الْحَقِّ فِي الرِّضَا وَالْغَضَبِ، وَأَسْأَلُكَ الْقَصْدَ فِي الْغِنَى وَالْفَقْرِ، وَأَسْأَلُكَ نَعِيماً لَا يَنْفَذُ، وَأَسْأَلُكَ قُرَّةَ عَيْنٍ لَا تَنْقَطِعُ، وَأَسْأَلُكَ الرِّضِا بَعْدَ الْقَضَاءِ، وَأَسْأَلُكَ بَرْدَ الْعَيْشِ بَعْدَ الْمَوْتِ، وَأَسْأَلُكَ لَذَّةَ النَّظَرِ إِلَى وَجْهِكَ وَالشَّوْقَ إِلَى لِقَائِكَ فِي غَيْرِ ضَرَّاءَ مُضِرَّةٍ وَلَا فِتْنَةٍ مُضِلَّةٍ، اللَّهُمَّ زَيِّنَّا بِزِينَةِ الْإِيمَانِ

 وَاجْعَلْنَا هُدَاةً مُهْتَدِينَ

O Allah! By Your Knowledge of the unseen and by Your Power over creation, let me live if life is good for me, and let me die if death is good for me; O Allah! I ask You to grant me (the blessing of having) fear of You in private and public; And I ask you (to make me utter) a statement of truth in times of contentment and anger; And I ask You for moderation when in a state of wealth and poverty; And I ask you for blessings that never ceases; And I ask You for the coolness of my eye that never ends; And I ask You (to make me pleased) after (Your) decree; Aand I ask You for a life of (ease, comfort, tranquility etc) after death; I ask You for the delight of looking at Your Face (i.e. in the Hereafter) and yearning to meet You without any harm and misleading trials (coming upon me); O Allah! Adorn us with the adornment of Eemaan, and make us (from those who are) guided and guiding (others). https://salaficentre.com/2021/01/01/o-allaah-let-me-live-if-life-is-good-for-me-and-let-me-die-if-death-is-good-for-me/
