Muhammad ibn Ali ibn Mahbub, from Ali ibn al-Sindi, from Muhammad ibn Amr ibn Said, from Muhammad ibn Yahya al-Sayrafi, from Muhammad ibn Sufyan, from a man, from Abu Abdillah عليه السلام, peace be upon him: I asked Imam al-Sadiq عليه السلام about the Prophet صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى bless him and his family, turning his cloak inside out when He صلى الله عليه وعلى آله وسلم prayed for rain (istisqa). Imam عليه السلام said: “It was a sign between Him صلى الله عليه وعلى آله وسلم and his companions, by which drought would be turned into abundance.”
