Volume 3, Book 48, Number 849:
Narrated Said bin Jubair:
A Jew from Hira asked me which one of the two periods Musa (i.e. Prophet Moses) completed. I
said, “I don’t know, (but wait) till I see the most learned ‘Arab and enquire him about it.” So, I went to
Ibn ‘Abbas and asked him. He replied, “Moses completed the longer and better period.” Ibn ‘Abbas ad –
ded, “No doubt, an apostle of Allah always does what he says.”
