Imam Abu Nasr bin As-Sabbagh stated in his book, Ash-Shamil, that the scholars agree that this Ayah ﴿5:45﴾ should be implemented, and the Imams agree that the man is killed for a woman whom he kills, according to the general indications of this Ayah. A Hadith that An-Nasa'i recorded states that the Messenger of Allah had this statement written in the book that he gave `Amr bin Hazm,

«أَنَّ الرَّجُلَ يُقْتَلُ بِالْمَرْأَة»

(The man is killed for the woman (whom he kills).) In another Hadith, the Messenger said,

«الْمُسْلِمُونَ تَتَكَافَأُ دِمَاؤُهُم»

(Muslims are equal regarding the sanctity of their blood.) This is also the opinion of the majority of the scholars. What further supports what Ibn As-Sabbagh said is the Hadith that Imam Ahmad recorded that Anas bin Malik said, "Ar-Rabi` (his aunt) broke the tooth of a girl, and the relatives of Ar-Rabi` requested the girl's relatives to forgive (the offender), but they refused. So, they went to the Prophet who ordered them to bring about retaliation. Anas bin An-Nadr, her brother, asked, `O Allah's Messenger! Will the tooth of Ar-Rabi` be broken' The Messenger of Allah said, `O Anas! The Book of Allah prescribes retaliation.' Anas said, `No, by Him Who has sent you with the Truth, her tooth will not be broken. ' Later the relatives of the girl agreed to forgive Ar-Rabi` and forfeit their right to retaliation. The Messenger of Allah said,

«إن من عباد الله من لو أقسم على الله لأبره»

(There are some of Allah's servants who, if they take an oath by Allah, Allah fullfils them.)'' It was recorded in the Two Sahihs.
