أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ إِسْمَاعِيلَ بْنِ سَعْدٍ اَلْأَشْعَرِيِّ قَالَ: سَأَلْتُ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يَلْمِسَ فَرْجَ جَارِيَتِهِ حَتَّى يَنْزِلَ اَلْمَاءُ مِنْ غَيْرِ أَنْ يُبَاشِرَ يَعْبَثُ بِهَا بِيَدِهِ حَتَّى تُنْزِلَ قَالَ« إِذَا أَنْزَلَتْ مِنْ شَهْوَةٍ فَعَلَيْهَا اَلْغُسْلُ».
Ahmad ibn Muhammad, from Isma'il ibn Sa’d al-Ash’ari, who said:
I asked al-Ridha عليه السلام about a man who touches the private part of his maidservant without direct sexual intercourse, playing with her with his hand until she ejaculates. Imam عليه السلام said: 'If she ejaculates due to arousal, ghusl becomes obligatory upon her.'"
