بَابُ مَا جَاءَ فِي قَوْلِ اللَّهِ تَعَالَى: {وَهُوَ الَّذِي يَبْدَأُ الْخَلْقَ ثُمَّ يُعِيدُهُ}
Sahih al-Bukhari 3190

Narrated `Imran bin Husain:

Some people of Bani Tamim came to the Prophet (ﷺ) and he said (to them), "O Bani Tamim! rejoice with glad tidings." They said, "You have given us glad tidings, now give us something." On hearing that the color of his face changed then the people of Yemen came to him and he said, "O people of Yemen ! Accept the good tidings, as Bani Tamim has refused them." The Yemenites said, "We accept them. Then the Prophet (ﷺ) started taking about the beginning of creation and about Allah's Throne. In the mean time a man came saying, "O `Imran! Your she-camel has run away!'' (I got up and went away), but l wish I had not left that place (for I missed what Allah's Messenger (ﷺ) had said).

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ جَامِعِ بْنِ شَدَّادٍ، عَنْ صَفْوَانَ بْنِ مُحْرِزٍ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ ـ رضى الله عنهما ـ قَالَ جَاءَ نَفَرٌ مِنْ بَنِي تَمِيمٍ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏"‏ يَا بَنِي تَمِيمٍ، أَبْشِرُوا ‏"‏‏.‏ قَالُوا بَشَّرْتَنَا فَأَعْطِنَا‏.‏ فَتَغَيَّرَ وَجْهُهُ، فَجَاءَهُ أَهْلُ الْيَمَنِ، فَقَالَ ‏"‏ يَا أَهْلَ الْيَمَنِ، اقْبَلُوا الْبُشْرَى إِذْ لَمْ يَقْبَلْهَا بَنُو تَمِيمٍ ‏"‏‏.‏ قَالُوا قَبِلْنَا‏.‏ فَأَخَذَ النَّبِيُّ صلى الله عليه وسلم يُحَدِّثُ بَدْءَ الْخَلْقِ وَالْعَرْشِ، فَجَاءَ رَجُلٌ فَقَالَ يَا عِمْرَانُ، رَاحِلَتُكَ تَفَلَّتَتْ، لَيْتَنِي لَمْ أَقُمْ‏.‏
