Jabir bin Abdullah reported the Messenger of Allah صلی اللہ علیہ وسلم as saying: Do not invoke curse on yourselves, and do not invoke curse on your children, and do not invoke curse on your servants, and do not invoke curse on your property, lest you happen to do it at a time when Allah is asked for something and grants your request. Abu Dawud said: This Hadith has a continuous chain of narrators, Ubadah bin Al-Walid bin Ubadah (did) met Jabir.
