48. From him, from Ahmad, from Al-Barqy, from Muhammad Bin Yahya, from Hammaad Bin usmaan who said: ‘Musa Bin Isa was in his house which was in the place of Sa’ee (nearby the Kaaba), overlooking it when he saw Abu Al-Hassan Musa  coming from Al-Marwa upon his  mule. So he ordered Ibn Hayyaaj, a man from Hamdaan who was very close to him  to go and hold on to the reins and make a claim for the mule. So he came up to him , held on to the reins, and staked a claim for the mule. Abu Al-Hassan  took his  feet off and dismounted from it and said to his  servant: ‘Take the saddle and hand (the mule) over to him’. He said, ‘And the saddle is mine as well’. So Abu Al-Hassan  said: ‘You are lying, for we  have clear proof that it is the saddle of Muhammad  Bin Ali , and as for the mule, so we  have bought it not so long ago and you know it, and what you are saying’.
