Prohibition of Calling a Muslim a Fasiq (Sinner)
① It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that he heard the Messenger of Allah (peace be upon him) say:
لا يرمي رجل رجلا بالفسق أو يرميه بالكفر إلا ارتدت عليه إن لم يكن صاحبه كذلك
“If a man accuses another of being a fasiq (sinner) or a disbeliever, and if that is not true, then this word will return upon the one who said it.”
Prohibition of Insulting a Muslim
① Sayyiduna Ibn Mas’ud رضي الله عنه narrates that the Messenger of Allah صلی اللہ علیہ وسلم said:
سباب المسلم فسوق، وقتاله كفر
“To insult a Muslim is an act of immorality, and to fight with him is disbelief.”
② It is narrated from Sayyiduna Abu Hurairah رضي الله عنه that the Messenger of Allah صلی اللہ علیہ وسلم said:
المستبان ما قالا فعلى الأول وفي رواية: فعلى البادئ منهما حتى يتعدى المظلوم
“When two people insult each other, the sin of what they say is upon the first person.” And in another narration: “The sin is upon the one who initiates it among the two, even if the oppressed person retaliates.”
Prohibition of Insulting the Air
① Sayyiduna Abu Hurairah رضي الله عنه narrates, I heard the Messenger of Allah صلی اللہ علیہ وسلم say:
إن هذه الريح من روح الله، تأتي بالرحمة وتأتي بالعذاب، فإذا رأيتموها فلا تسبوها، وسلوا الله تعالى خيرها، واستعيذوا بالله من شرها
“This is the wind of Allah’s mercy; it brings mercy and also brings punishment. So when you see it, do not speak ill of it, but seek goodness and protection from its evil from Allah Almighty.”
Prohibition of Holding Grudge and Enmity
① Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace be upon him) said:
تفتح أبواب الجنة يوم الخميس ويوم الاثنين، فيغفر لكل عبد لا يشرك بالله شيئا، إلا رجلا كانت بينه وبين أخيه شحناء، فيقال: أنظروا هذين حتى يصطلحا
“On the days of Thursday and Monday, the gates of Paradise are opened, and every person who does not associate partners with Allah is forgiven except for the one who harbors enmity against his brother. Then it is said: Give these two respite until they reconcile.”
② Sayyiduna Abu Hurairah (may Allah be pleased with him) also narrates from the Messenger of Allah (peace be upon him) that he said:
تعرض أعمال الناس فى كل جمعة مرتين: يوم الاثنين ويوم الخميس، فيغفر لكل عبد مؤمن إلا عبدا بينه وبين أخيه شحناء، فيقال: اتركوا أو أركوا هذين حتى يفيئا
“On Friday, the deeds of people are presented twice, on Monday and Thursday, so every believing servant is forgiven except for the one who has enmity with his brother. And it is said: Leave these two or postpone their matter until they reconcile.”
