Hadith.1496 - Abu Basir asked Imam Jafar ibn Muhammad Al-Sadiq عليه السلام about the thunder, saying, "What does it say?" Imam عليه السلام said: "It is like a man among the camels who drives them, saying 'Hai, Hai,' just as it is." I asked: "May I be your ransom, what about the lightning?" Imam عليه السلام said: "Those are the whips of the angels striking the clouds, driving them to the place where Allah سبحانه وتعالى, the Mighty and Glorious, has decreed the rain to fall."
