Jabir bin'Abdullah (RA) reported that some people from amongst the Jews said to Allah's Messenger ( صلی اللہ علیہ وسلم ) Abu'l-Qasim as-Sam-u-'Alaikum, whereupon he said: Wa 'Alaikum. A'isha was enraged and asked him (Allah's Apostle) ( صلی اللہ علیہ وسلم ) whether he had not heard what they had said. He said, I did hear and I retorted to them (and the curse that I invoked upon them would receive response from Allah), but (the curse that they invoked upon us) would not be responded.
