Prohibition of a person saying “People are destroyed”
① It is narrated from Sayyiduna Abu Hurairah رضي الله عنه that the Messenger of Allah صلی اللہ علیہ وسلم said:
إذا سمعتم الرجل يقول: هلك الناس فهو أهلكهم
“When you hear a person saying ‘People are destroyed,’ then he is the most destroyed among them all.”
Abu Ishaq رحمه الله states, I do not know whether the fatha on the kaf in “أَهْلَكَهُمْ” means “He destroyed them” or the kasra on the kaf in “أَهْلَكُهُمْ” means “He is the most destroyed among them all.”
Prohibition of a person saying Masha Allah and Masha so-and-so
① Sayyiduna Hudhaifah رضي الله عنه narrates from the Prophet Muhammad صلی اللہ علیہ وسلم, who said:
لا تقولوا: ما شاء الله وشاء فلان، ولكن قولوا: ما شاء الله ثم شاء فلان
“Do not say ‘Whatever Allah wills and whatever so-and-so wills,’ rather say: ‘Whatever Allah wills, then so-and-so wills.'”
Prohibition of saying “_جاشت نفسي” by a person
① Sayyiduna Sahl bin Hunayf رضي الله عنه reports that the Messenger of Allah صلی اللہ علیہ وسلم said:
لا يقولن أحدكم: خبثت نفسي، ولكن ليقول: لقست نفسي
“None of you should say: ‘My soul has become evil,’ rather say: ‘My heart is uneasy.'”
② It is narrated from Sayyidah Aisha رضي الله عنها that the Messenger of Allah صلی اللہ علیہ وسلم said:
لا يقولن أحدكم: جاشت نفسي، ولكن لقست نفسي
“None of you should say ‘جاشت نفسي‘, rather say: ‘لقست نفسي‘ (both mean the same: heart palpitations).”
