5. Muhammad ibn Yahya, from Ahmad ibn Muhammad ibn Isa, from Muhammad ibn Isa, from Mansur, from Hisham ibn Salim, narrated from Abu Abdillah al-Sadiq (as): He was asked about whether the Bedouins (Arab nomads) are obligated to engage in jihad. He replied, "No, unless there is a fear for Islam, in which case they can be sought for assistance." I then asked, "Do they receive any part of the jizya (tribute)?" He said, "No."
