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.
أَنَّ فِي حَدِيثِ شُعْبَةَ ثُمَّ اجْتَهَدَ وَلَمْ يَقُلْ وَإِنْ لَمْ يُنْزِلْ
