۞
The Prophet (SAWA) said, 'If any of you ever insults his fellow brother, he must not insult his family or his father or mother. He can only say - if he knows these flaws for certain - 'You are indeed a miser, or you are indeed a coward, or you are indeed a liar' only if he is certain of the existence of these traits.
رسولُ اللّه صلى الله عليه و آله : إذا شَتَمَ أحَدُكُم أخاهُ فلا يَشتِمْ عَشِيرَتَهُ ، ولا أباهُ ، ولا اُمَّهُ ، ولكنْ لِيَقُلْ إن كانَ يَعلَمُ ذلك : إنّكَ لَبَخِيلٌ ، وإنّكَ لَجَبانٌ ، وإنّكَ لَكَذُوبٌ ، إن كانَ يَعلَمُ ذلكَ مِنهُ.
