Imran bin Husayn reported,

I was with the Prophet ﷺ when a group from the tribe of Banu Tamim came to him.He said, "Receive the good news, Banu Tamim."They replied, "You have given us good news, so now give us something."Then some people from Yemen entered, and he said to them, "Receive the good news, people of Yemen, since Banu Tamim would not accept it."They said, "We accept it. We have come to you to gain understanding in the religion and to ask you about the beginning of this matter, what it was."He said, "Allah existed and there was nothing before Him, and His Throne was upon the water. Then He created the heavens and the earth, and He wrote in the Record everything."Then a man came to me and said, "Imran, catch up with your camel, for it has gone off."So I set out searching for it, but the mirage cut off my view of it. By Allah, I wished it had simply gone and that I had not gotten up.

حدثنا عبدان قال أخبرنا أبو حمزة عن الأعمش عن جامع بن شداد عن صفوان بن محرز

عن عمران بن حصين قال

إني عند النبي ﷺ إذ جاءه قوم من بني تميم فقال اقبلوا البشرى يا بني تميم قالوا بشرتنا فأعطنا فدخل ناس من أهل اليمن فقال اقبلوا البشرى يا أهل اليمن إذ لم يقبلها بنو تميم قالوا قبلنا جئناك لنتفقه في الدين ولنسألك عن أول هذا الأمر ما كان قال كان الله ولم يكن شيء قبله وكان عرشه على الماء ثم خلق السموات والأرض وكتب في الذكر كل شيء ثم أتاني رجل فقال يا عمران أدرك ناقتك فقد ذهبت فانطلقت أطلبها فإذا السراب ينقطع دونها وايم الله لوددت أنها قد ذهبت ولم أقم
