A lot of kafirs pretending to be Muslim teachers of ihsan have lately been talking about cuddly huggles with their kafir brothers and sisters.
This verse from the Holy Quran is sufficient for Muslims to take heed from:
قَدْ كَانَتْ لَكُمْ أُسْوَةٌ حَسَنَةٌ فِي إِبْرَاهِيمَ وَالَّذِينَ مَعَهُ إِذْ قَالُوا لِقَوْمِهِمْ إِنَّا بُرَآءُ مِنكُمْ وَمِمَّا تَعْبُدُونَ مِن دُونِ اللَّهِ كَفَرْنَا بِكُمْ وَبَدَا بَيْنَنَا وَبَيْنَكُمُ الْعَدَاوَةُ وَالْبَغْضَاءُ أَبَدًا حَتَّىٰ تُؤْمِنُوا بِاللَّهِ وَحْدَهُ إِلَّا قَوْلَ إِبْرَاهِيمَ لِأَبِيهِ لَأَسْتَغْفِرَنَّ لَكَ وَمَا أَمْلِكُ لَكَ مِنَ اللَّهِ مِن شَيْءٍ ۖ رَّبَّنَا عَلَيْكَ تَوَكَّلْنَا وَإِلَيْكَ أَنَبْنَا وَإِلَيْكَ الْمَصِيرُ
Translation of meaning: Indeed, an excellent example has been set up for you, in Ibraahiim and those with him [i.e., those who declared faith in Allah following Ibraahiim], when they declared to their people, “We are aloof from you and that you worship besides Allah, we reject you and there has appeared enmity and hatred/grudge between us and you until forever unless you believe in Allah, the one and only” except Ibraahiim’s saying to his father, “I shall indeed ask for forgiveness for you* and I am not the possessor [of any benefit] to you in front of Allah; our Lord! In You do we place our trust, and to You do we turn, and to You is our final return.**” (Holy Quran 60:4)
* This act of Ibraahiim, ‘ala nabiyyina wa ‘alaihis salam, is not to be followed as expressly instructed by the Quran. Ibraahiim said that on the basis of a promise he had made. But later when it was manifest to Ibraahiim, ‘alaihis salam, that he was firm upon disbelief, Ibraahiim, ‘alaihis salam, expressed disdain from him. Therefore, it is NOT allowed for anyone to pray for the forgiveness of a kafir relative, no matter how close.
** This – [Our Lord! In You do we place our trust, and to You do we turn, and to You is our final return] – is also the dua of our father, Prophet Ibraahiim, ‘alaihis salam, and the believers who were with him, and this dua should be made by Muslims.
In Arabic, the word ‘father’ can also be used metaphorically for uncles, elders etc. as is clearly evident from other places in the Quran. There are narrations that the one who raised Abraham since childhood and he was adamant on paganhood, was actually his uncle.
The Quran itself states that that aspect of our father Abraham’s example (praying for his kafir parent’s forgiveness) is not to be followed. In addition, Abraham himself abstained from this once he saw that this person was not budging and accepting islam.
The clear message in this verse is that it is forbidden to bear any affinities to kafirs, even if they are one’s parents. A Muslim is someone who does not commit injustice, but that doesn’t mean s/he needs to bear affinities to kuffaar, even if they be his/her kith and kin.
