حَدَّثَنَا مُحَمَّدُ بْنُ عَمْرِو بْنِ عَبَّادِ بْنِ جَبَلَةَ ، حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عَدِيٍّ ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنِي وَهْبُ بْنُ جَرِيرٍ ، كِلاَهُمَا عَنْ شُعْبَةَ ، عَنْ قَتَادَةَ ، بِهَذَا الإِسْنَادِ مِثْلَهُ غَيْرَ أَنَّ فِي حَدِيثِ شُعْبَةَ " ثُمَّ اجْتَهَدَ " وَلَمْ يَقُلْ " وَإِنْ لَمْ يُنْزِلْ " .
This hadith is narrated by Qatida with the same chain of transmitters, but with minor alterations. Here instead of the word - (jahada, (ijtahada) has been used, and the words;" Even if there is no orgasm" have been omitted.
