It was narrated from 'Abbad bin Tamim:
Sufyan said: 'I asked 'Abdullah bin Abi Bakr who said: I heard it from Abbad bin Tamim who narrated it from his father, that 'Abdullah bin Zaid, who was shown the call to prayer (in a dream) said: 'The Messenger of Allah (ﷺ) went out to the prayer place to pray for rain. He faced the kiblah and turned his cloak around and prayed two rak'ahs.'
