عَنْهُ عَنْ مُعَاوِيَةَ بْنِ حُكَيْمٍ عَنْ سُلَيْمَانَ بْنِ جَعْفَرٍ عَنْ أَبِيهِ قَالَ: دَخَلَ رَجُلٌ مِنْ أَهْلِ اَلشَّامِ عَلَى أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ فَقَالَ لَهُ« إِنَّ أَوَّلَ مَنْ سَبَقَ إِلَى اَلْجَنَّةِ بِلاَلٌ» قَالَ وَ لِمَ قَالَ« لِأَنَّهُ أَوَّلُ مَنْ أَذَّنَ»
From him, from Mu'awiyah ibn Hakim, from Sulayman ibn Ja'far, from his father who said:
A man from the people of Sham entered upon Abu Abdillah عليه السلام, peace be upon him, and said to Imam عليه السلام: "Indeed, the first to precede to Paradise was Bilal." He asked: "And why is that?" Imam عليه السلام said: "Because he was the first to give the Adhan."
