This hadith has been reported on the authority of Safiyya, the wife of Allah's Apostle ( صلی اللہ علیہ وسلم ), through another chain of transmitters (and the words) are:
She went to Allah's Apostle ( صلی اللہ علیہ وسلم ) to visit him as he was observing I'tikaf in the mosque during Ramadan. She talked with him for some time and then stood up to go back and Allikh's Apostle ( صلی اللہ علیہ وسلم ) stood up in order to bid her good-bye. The rest of the hadith is the same except with the variation of the words that Allah's Apostle ( صلی اللہ علیہ وسلم ) said: Satan penetrates in man like the penetration of blood (in every part of body).
