Abd ibn Humayd narrated to us, Ahmad ibn Yunus narrated to us, on the authority of Abu Bakr ibn Ayyash, on the authority of Abu Ishaq, on the authority of Al-Bara’, he said: A man came to The Messenger of God, may God’s prayers and peace be upon him, and he said, O Messenger of God: (They ask you for a fatwa. Say, “God gives you a fatwa regarding the calamity.”) So the Prophet, may God bless him and grant him peace, said to him. He said: “The miracle of summer will reward you.”
