(21) باب إِذَا ادَّعَى أَوْ قَذَفَ فَلَهُ أَنْ يَلْتَمِسَ الْبَيِّنَةَ، وَيَنْطَلِقَ لِطَلَبِ الْبَيِّنَةِ
Narrated Ibn `Abbas:
Hilal bin Umaiya accused his wife before the Prophet (ﷺ) of committing illegal sexual intercourse with Sharik bin Sahma.' The Prophet (ﷺ) said, "Produce a proof, or else you would get the legal punishment (by being lashed) on your back." Hilal said, "O Allah's Messenger (ﷺ)! If anyone of us saw another man over his wife, would he go to search for a proof." The Prophet (ﷺ) went on saying, "Produce a proof or else you would get the legal punishment (by being lashed) on your back." The Prophet (ﷺ) then mentioned the narration of Lian (as in the Holy Book). (Surat-al-Nur: 24)
