عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ قَالَ: كَانَ بِالْمَدِينَةِ رَجُلَانِ أَحَدُهُمَا يَلْحَدُ وَالْآخَرُ لَا يَلْحَدُ. فَقَالُوا: أَيُّهُمَا جَاءَ أَوَّلًا عَمِلَ عَمَلَهُ. فَجَاءَ الَّذِي يَلْحَدُ فَلَحَدَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ. رَوَاهُ فِي شَرْحِ السّنة

‘Urwa b. az-Zubair said there were two men in Medina, one of whom made a niche when digging a grave, the other of whom did not. The people said that the one who came first should do as he was accustomed to do, and the one who made a niche came and made one for God’s messenger. transmitted it in Sharh as-sunna.
