A man asked the Messenger of Allah ﷺ: Is there any food from which I should keep myself away? I heard the Messenger of Allah ﷺ say: Anything which creates doubt should not occur in your mind by which you resemble Christianity. (Using translation from Abū Dāʾūd 3784)
سَمِعْتُ رَسُولَ اللهِ ﷺ وَسَأَلَهُ رَجُلٌ فَقَالَ إِنَّ مِنَ الطَّعَامِ طَعَامًا أَتَحَرَّجُ مِنْهُ فَقَالَ لَا يَخْتَلِجَنَّ فِي نَفْسِكَ شَيْءٌ ضَارَعْتَ فِيهِ النَّصْرَانِيَّةَ وَرُوِيَ فِي ذَلِكَ أَيْضًا عَنْ عَدِيِّ بْنِ حَاتِمٍ عَنِ النَّبِيِّ ﷺ
