Hadith 3519

He reported God’s Messenger as saying, “If anyone points a piece of iron at his brother the angels will curse him till he puts it down, even if he is his brother who has the same father and mother.” Bukhari transmitted it.

وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ أَشَارَ إِلَى أَخِيهِ بِحَدِيدَةٍ فَإِنَّ الْمَلَائِكَةَ تَلْعَنُهُ حَتَّى يَضَعَهَا وَإِنْ كَانَ أخاهُ لأبيهِ وَأمه» . رَوَاهُ البُخَارِيّ
