Imran bin Husayn reported,

I came to the Prophet ﷺ and tied up my camel at the door. A group from Banu Tamim came to him, and he said, "Accept the good news, Banu Tamim."They replied, "You have given us good news, so give us something." He repeated this twice.Then a group from the people of Yemen came to him, and he said, "Accept the good news, people of Yemen, since Banu Tamim have not accepted it."They said, "We accept it, Messenger of Allah." Then they said, "We have come to ask you about this matter."He said, "Allah existed and there was nothing besides Him. His Throne was upon the water, and He wrote everything in the Record, then He created the heavens and the earth."Just then a caller called out, "Your camel has gone, son of Husayn." So I set off after it, but the mirage was already cutting it off from view. By Allah, I wish I had left it alone.

Sahih

عن عمران بن حصين قال

دخلت على النبي ﷺ وعقلت ناقتي بالباب، فأتاه ناس من بني تميم فقال: اقبلوا البشرى يا بني تميم. قالوا: قد بشرتنا فأعطنا- مرتين-، ثم دخل عليه ناس من أهل اليمن فقال: اقبلوا البشرى يا أهل اليمن إذ لم يقبلها بنو تميم. قالوا: قد قبلنا يا رسول الله، قالوا جئناك نسألك هذا الأمر، قال: كان الله ولم يكن شيء غيره، وكان عرشه على الماء، وكتب في الذكر كل شيء، وخلق السماوات والأرض. فنادى مناد: ذهبت ناقتك يا ابن الحصين، فانطلقت فإذا هي: يقطع دونها السراب فوالله لوددت أني كنت تركتها.
