It is narrated from Sayyiduna Sa’ib (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: Whoever unjustly frightens the people of Madinah, Allah will impose fear upon him. Upon him will be the curse of Allah, His angels, and all mankind, and on the Day of Resurrection, Allah will not accept any obligatory or voluntary act from him.
