The moon split while we were in Mecca, and the disbelievers of Quraysh from the people of Mecca said, "This is magic by which the son of Abu Kabsha has bewitched us. Wait for the travelers to arrive. If they tell you they saw the same thing you saw, then it is true. Otherwise, you have been deceived."He said, Not a single traveler came from any direction without informing them that they had seen exactly what the people of Mecca had seen.
انشق القمر ونحن بمكة فقال كفار قريش من أهل مكة: هذا سحر سحرنا به ابن أبي كبشة، فانظروا إلى السفار يأتونكم فإن أخبروكم أنهم رأوا مثل ما رأيتم، وإلا فقد كذبتم قال: فما جاءهم أحد من وجه من الوجوه إلا أخبرهم أنهم رأوا مثل ما رأوا.
Abu Dawud Tayalisi (293), Bazzar (1971), and Shashi in his Musnad (404) - and this is his wording - and Bayhaqi in Dalail (2/266) all narrated it, all of them through the route of Mughira (he is Ibn Miqsam Dabbi), from Abu Duha (whose name is Muslim bin Sabih), from Masruq, from Abdullah, and he mentioned it. Its chain is sahih. Bukhari mentioned it as a mualaq narration following hadith (3869), from Abu Duha, from Masruq, from Abdullah, saying, it split apart in Makkah.
