Mishkat al-Masabih 3 Purification كتاب الطهارة 248

وَعَنْ مُعَاذِ بْنِ جَبَلٍ قَالَ: قُلْتُ: يَا رَسُول الله مَا تحل لِي مِنِ امْرَأَتِي وَهِيَ حَائِضٌ؟ قَالَ: «مَا فَوْقَ الْإِزَارِ وَالتَّعَفُّفُ عَنْ ذَلِكَ أَفْضَلُ» . رَوَاهُ رَزِينٌ وَقَالَ مُحْيِي السُّنَّةِ: إِسْنَادُهُ لَيْسَ بِقَوِيٍّ

Mu’adh b. Jabal said that he asked God’s messenger what was lawful for him in his wife when she was menstruating, and he replied, “What is above the waist-wrapper, but to abstain from that is better.” Razin transmitted it and Muhyi as-Sunna said that its insad is not strong.
