At this time, a group of people came out who were wearing turbans and looked like those of the Indian gypsies. * *I asked Abu Ja`far (peace be upon him) about them saying, 'May Allah take my soul in the service of your cause. Today it took me a long time to receive permission to meet you.
I saw a group of people coming out with turbans on that I did not recognize.' * He said, 'Do you know, O Sa`d, who they were?' I replied, 'No, I do not know.' The Imam (peace be upon him) said, 'They were your brethren in religion from among the Jinn.
They come to us for religious instructions, to learn the lawful and unlawful matters and the principles of their religion.'” Hadith 4 مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ إِبْرَاهِيمَ بْنِ أَبِي الْبِلادِ عَنْ سَدِيرٍ الصَّيْرَفِيِّ قٌالَ: أَوْصانِي أَبُو جَعْفَرٍ (عَلَيْهِ السَّلاٌمُ) بِحَوائِجَ لَهُ بِالْمَدِينَةِ فَخَرَجْتُ فَبَيْنا أَنا بَيْنَ فَجِّ الرَّوْحٌاءِ عَلَى راحِلَتِي إِذٌا إِنْسٌانٌ يَلْوِي ثَوْبَهُ.
وَ فِي رِوايَةٍ أُخْرَى قالَ: إِنَّ لَنا أَتْبَاعاً مِنَ الْجِنِّ كَما أَنَّ لَنا أَتْباعاً مِنَ الإِنْسِ فَإِذا أَرَدْنا أَمْراً بَعَثْناهُمْ. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Ibrahim ibn Abu'l Balad from Sadir al-Sayrafi, who has said the following: “ Abu Ja`far (peace be upon him) asked me to help him with a few things in Madina. I left and when I reached Fajj al-Rawha` (name of a place) a man waved to me with his clothes.
The narrator said that I turned to him and I thought he was thirsty. I offered him a cup but he declined saying, 'I do not need it.' He gave me a letter whose ink was not dry yet. The narrator said that when I looked at it, it had the seal of Abu Ja`far (peace be upon him) on it.
