أَخْبَرَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ عُثْمَانَ بْنِ الْأَسْوَدِ، عَنْ مُجَاهِدٍ: فَأْتُوهُنَّ مِنْ حَيْثُ أَمَرَكُمُ اللَّهُ سورة البقرة آية 222، قَالَ: "أُمِرُوا أَنْ يَأْتُوا مِنْ حَيْثُ نُهُوا".
It is narrated from Mujahid, may Allah have mercy on him: The meaning of «﴿فَأْتُوهُنَّ مِنْ حَيْثُ أَمَرَكُمُ اللَّهُ﴾» [بقره: 222/2] is that they have been commanded that after purification, fulfill your need at the same place from which you were prevented. (That is, intercourse is permitted and avoid the anus.)
