Maʿānī al-ʾAkhbār > The meaning of the saying of al-Sadiq, peace be upon him: «There is no jalb, nor janb, nor shighar in Islam»
Hadith #1

حدثنا أبي - رحمه الله - قال: حدثنا سعد بن عبد الله، عن محمد بن الحسين بن أبي الخطاب، عن جعفر بن رشيد، عن غياث، قال: سمعت أبا عبد الله عليه السلام يقول: لا جلب ولا جنب ولا شغار في الاسلام، قال: الجلب الذي يجلب مع الخيل يركض معها، والجنب الذي يقوم في أعراض الخيل فيصيح بها، والشغار كان يزوج الرجل في الجاهلية ابنته بأخته.

1. We were told by my father, may Allah grant him mercy, that he said: We were told by Sa’d bin Abdullah, from Muhammed bin Hussain bin Abi’l-Khattab, from Ja’far bin Rasheed, from Ghiyath, that he said: I heard Abu Abdillah, peace be upon him, say: There is no jalb, nor janb, nor shighar in Islam. He said: Jalb is that which is drawn with horses, running with them. Janb refers to the one who stands at the edge of the (gathering of) horses and calls for them. Shighar is that a man marries, in the Jahiliya, a daughter (of another man) by (marrying off) his sister (to the other man).
