Volume 7, Book 65, Number 323:
Narrated Sad:
I was one of (the first) seven (who had embraced Islam) with Allah’s Apostle and we had nothing
to eat then, except the leaves of the Habala or Hubula tree, so that our stool used to be similar to that
of sheep. Now the tribe of Bani Asad wants to teach me Islam; I would be a loser and all my efforts
would be in vain (if I learn Islam anew from them).
