AbdurRahman ibn Ka'b ibn Malik said: When Ka'b ibn Malik heard the call to prayer on Friday, he prayed for As'ad ibn Zurarah. I asked him: What is the matter that when you hear the call to prayer, you pray for As'ad ibn Zurarah? He replied: This is because he held the Friday prayer for the first time for us at Hazm an-Nabit of Harrah belonging to Banu Bayadah in Naqi', called Naqi' al-Khadumat. I asked him: How many were you at that time ? He said: Forty.  

أبو داود:١٠٦٩ – حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا ابْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ عَنْ مُحَمَّدِ بْنِ أَبِي أُمَامَةَ بْنِ سَهْلٍ عَنْ أَبِيهِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبِ بْنِ مَالِكٍ وَكَانَ قَائِدَ أَبِيهِ بَعْدَ مَا ذَهَبَ بَصَرُهُ عَنْ أَبِيهِ كَعْبِ بْنِ مَالِكٍ أَنَّهُ كَانَ إِذَا سَمِعَ النِّدَاءَ يَوْمَ الْجُمُعَةِ تَرَحَّمَ لأَسْعَدَ بْنِ زُرَارَةَ فَقُلْتُ لَهُ إِذَا سَمِعْتَ النِّدَاءَ تَرَحَّمْتَ لأَسْعَدَ بْنِ زُرَارَةَ قَالَ

لأَنَّهُ أَوَّلُ مَنْ جَمَّعَ بِنَا فِي هَزْمِ النَّبِيتِ مِنْ حَرَّةِ بَنِي بَيَاضَةَ فِي نَقِيعٍ يُقَالُ لَهُ نَقِيعُ الْخَضِمَاتِ قُلْتُ كَمْ أَنْتُمْ يَوْمَئِذٍ قَالَ أَرْبَعُونَ

[Machine] "O my son, the happiest person who ever joined us in the city before the Prophet's arrival was during the defeat of a group from the Banu Bayadha tribe in the valleys of Naki'in. I asked, 'How many of you were there then?' He said, 'We were forty men.'"

يَا بُنَيَّ إِنَّ «أَسْعَدَ أَوَّلُ مَنْ جَمَعَ بِنَا بِالْمَدِينَةِ قَبْلَ مَقْدِمِ النَّبِيِّ ﷺ فِي هَزْمِ مِنْ حَرَّةِ بَنِي بَيَاضَةَ فِي نَقِيعِ الْهَضبَاتِ» قُلْتُ وَكَمْ كُنْتُمْ يَوْمَئِذٍ؟ قَالَ أَرْبَعِينَ رَجُلًا
