1ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ أَبِي أَيُّوبَ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ إِنَّ الْيَهُودَ سَأَلُوا رَسُولَ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) فَقَالُوا انْسِبْ لَنَا رَبَّكَ فَلَبِثَ ثَلاثاً لا يُجِيبُهُمْ ثُمَّ نَزَلَتْ قُلْ هُوَ الله أَحَدٌ إِلَى آخِرِهَا. وَرَوَاهُ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ أَبِي أَيُّوبَ.

1. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from abu Ayyub from Muhammad ibn Muslim from abu ‘Abdallah (a.s.) who has said the following. “The Jews asked the Messenger of Allah (s.a.), ‘Describe for us the genealogy- of your Lord.’” The Prophet waited for three days and gave no reply. Then the following verses were revealed to him: In the Name of Allah, the Beneficent, the Merciful (Muhammad), say, “He is the only God (112:1). God is Absolute (112:2). He neither begets nor was He begotten (112:3). There is no one equal to Him (112:4). The same Hadith has been narrated by Muhammad ibn Yahya from Ahmad ibn Muhammad from Ali ibn al-Hakam from abu Ayyub.
