When Mecca was conquered, the Messenger of Allah ﷺ got up and said: If a relative of anyone is killed, he will have a choice between two : he (the slayer) will either pay the blood-wit or he will be killed. A man of the Yemen called Abu Shah stood up and said: Write for me, Messenger of Allah. The narrator al-'Abbas (b. al-Walid) said: Write to me, (you people). The Messenger of Allah ﷺ said: Write (you people), for Abu Shah. These are the wordings of the tradition of Ahmad. Abu Dawud said: Write (you people), for me, that is, the address of the Prophet ﷺ.
لَمَّا فُتِحَتْ مَكَّةُ قَامَ رَسُولُ اللَّهِ ﷺ فَقَالَ مَنْ قُتِلَ لَهُ قَتِيلٌ فَهُوَ بِخَيْرِ النَّظَرَيْنِ إِمَّا أَنْ يُودَى أَوْ يُقَادَ فَقَامَ رَجُلٌ مِنْ أَهْلِ الْيَمَنِ يُقَالُ لَهُ أَبُو شَاهٍ فَقَالَ يَا رَسُولَ اللَّهِ اكْتُبْ لِي قَالَ الْعَبَّاسُ اكْتُبُوا لِي فَقَالَ رَسُولُ اللَّهِ ﷺ اكْتُبُوا لأَبِي شَاهٍ وَهَذَا لَفْظُ حَدِيثِ أَحْمَدَ
