AFFECTION & INCLINATION TOWARDS NON BELIEVERS
From many Qur’anic verses and traditions, we can conclude that a Muslim individual is required to steer clear of showing love, sharing mutual affection, and inclining towards the nonbelievers as well as assimilating himself/herself to them and following their ways. In this respect, Allah the All-exalted says (in the Holy Qur’an):
قَدْ كَانَتْ لَكُمْ اُسْوَةٌ حَسَنَةٌ فِىْۤ اِبْرٰهِيْمَ وَالَّذِيْنَ مَعَهُ اِذْ قَالُوْا لِقَوْمِهِمْ اِنَّا بُرَءَاۤؤُ مِنْكُمْ وَ مِمَّا تَعْبُدُوْنَ مِنْ دُوْنِ اللّٰهِ كَفَرْنَا بِكُمْ وَ بَدَا بَيْنَنَا وَ بَيْنَكُمُ الْعَدَاوَةُ وَالْبَغْضَاۤءُ اَبَدًا۔
“Indeed, there is for you a good example in Abraham and those with him when they said to their people: ‘Surely, we are clear of you and of what you serve besides Allah. We declare ourselves to be clear of you, and enmity and hatred have appeared between us and you forever.”
Shaykh al-Saduq has reported Imam al-Sadiq (‘a) as saying, “Almighty Allah inspired to one of His prophets to convey this message to the believers: Do not dress yourselves with the costumes of My enemies, do not eat what they eat, and do not behave like them; lest, you will be My enemies as they are.”
In view of that, traditions have forbidden from certain acts for no reason more than avoiding imitating the nonbelievers.
