Beware of wearing clothes that have a cross on them!

عن عَائِشَةَ رضى الله عنها أَنَّ النَّبِيَّ ﷺ لَمْ يَكُنْ يَتْرُكُ فِي بَيْتِهِ شَيْئًا فِيهِ تَصَالِيبُ إِلاَّ نَقَضَهُ‏.‏ A'ishah (may Allāh be pleased with her) reported that the Prophet ﷺ would not leave in his house anything containing crosses except that he obliterated it. [Sahih Bukhari - 5952]
