The following are the transcripts from ziyarat al- ashura,

فَلَعَنَ ٱللَّهُ أُمَّةً أَسَّسَتْ أَسَاسَ ٱلظُّلْمِ وَٱلْجَوْرِ عَلَيْكُمْ أَهْلَ ٱلْبَيْتِ
وَلَعَنَ ٱللَّهُ ٱلْمُمَهِّدِينَ لَهُمْ
بِٱلتَّمْكِينِ مِنْ قِتَالِكُمْ
بَرِئْتُ إِلَىٰ ٱللَّهِ وَإِلَيْكُمْ مِنْهُمْ
وَمِنْ أَشْيَاعِهِمْ وَأَتْبَاعِهِمْ وَأَوْلِيَائِهِمْ

So, may Allah curse the people who laid the basis of persecution and wronging against you, O Members of the Household. May Allah curse those who paved the way for them to do so and who made possible for them to fight against you. I repudiate them in the presence of Allah and You and I repudiate their devotees, followers, and loyalists.

Also in Quran, surah al-mumtahina verse no. 9 and in surah al mujadila verse no. 22,

إِنَّمَا يَنْهَاكُمُ اللَّهُ عَنِ الَّذِينَ قَاتَلُوكُمْ فِي الدِّينِ وَأَخْرَجُوكُم مِّن دِيَارِكُمْ وَظَاهَرُوا عَلَىٰ إِخْرَاجِكُمْ أَن تَوَلَّوْهُمْ ۚ وَمَن يَتَوَلَّهُمْ فَأُولَـٰئِكَ هُمُ الظَّالِمُونَ

Allah forbids you only in regard to those who made war against you on account of religion and expelled you from your homes and supported [the polytheists of makkah] in your expulsion, that you make friends with them, and whoever makes friends with them it is they who are the wrongdoers.

لَّا تَجِدُ قَوْمًا يُؤْمِنُونَ بِاللَّهِ وَالْيَوْمِ الْآخِرِ يُوَادُّونَ مَنْ حَادَّ اللَّهَ وَرَسُولَهُ وَلَوْ كَانُوا آبَاءَهُمْ أَوْ أَبْنَاءَهُمْ أَوْ إِخْوَانَهُمْ أَوْ عَشِيرَتَهُمْ ۚ أُولَـٰئِكَ كَتَبَ فِي قُلُوبِهِمُ الْإِيمَانَ وَأَيَّدَهُم بِرُوحٍ مِّنْهُ ۖ وَيُدْخِلُهُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ خَالِدِينَ فِيهَا ۚ رَضِيَ اللَّهُ عَنْهُمْ وَرَضُوا عَنْهُ ۚ أُولَـٰئِكَ حِزْبُ اللَّهِ ۚ أَلَا إِنَّ حِزْبَ اللَّهِ هُمُ الْمُفْلِحُونَ

You will not find a people believing in Allah and the Last Day endearing those who oppose Allah and His Apostle even though they were their own parents, or children, or brothers, or kinsfolk. [For] such, He has written faith into their hearts and strengthened them with a spirit from Him. He will admit them into gardens with streams running in them, to remain in them [forever], Allah is pleased with them, and they are pleased with Him. They are Allah’s confederates. Look! The confederates of Allah are indeed felicitous!

Now it has been crystal clear that the Israeli brand are openly supporting this genocide and there is no room for any doubt about it and if anyone needs prove I am ready to give that too further, this verses and those transcript from ziyarat al-ashura made it very clear that we have to do tabbara on them those who supports injustice and oppression! The Israeli Brands and other brands supporting genocide are clearly laying a foundation and supporting this genocide! To tabbara on them is wajib on every muslim and the one who doesn’t do tabbara on them is same as those oppressors and murderers and it is they with whom allah is not pleased with as per the verses of quran mentioned above, now tabbara i.e disassociation has 3 main components, one is physical disassociation which includes boycotting them and not supporting them, second one is verbal disassociation in this we have to make people aware about boycotting such products and ask them to boycott it too! And the last component is to not to have any soft corner in our heart for such oppressors! Indeed if one does all of this then allah is pleased with you as well as your imam hussain(a)! And you will be granted jannah! And you will be considered among the party of allah as per verse 22 of sural al-mujadila! So boycotting such brands are something which is backed by quran and our traditions, it is something which is within our shariah and is not an innovated act, also is wajib on each and every muslim.
