This statement forms part of the ḥadith related by ʿAmr ibn Shuʿayb from his father, from his grandfather. It was quoted in full under section (5), where its chain of transmission was also discussed.
Ibn al-Athīr says in al-Nihāyah: “They say: nashadtu al-ḍāllah, I am nāshid—when one is looking for a stray; and anshadtu-hā—when one has identified it. The word is derived from nashīd, meaning to raise the voice.”
The ḥadith therefore proves that asking about a lost animal inside the mosque is forbidden, provided the enquiry is made in a loud voice. This is the view adopted by Ibn Ḥazm and al-Ṣanʿānī in Sabil al-Salām, and it is, God willing, the correct position, for it is the plain sense of the prohibition. Moreover, the Prophet (peace and blessings be upon him) ordered that the following words be addressed to such an announcer as a form of reprimand:
“As for the other ḥadith: A Bedouin came after the Prophet (peace and blessings be upon him) had performed the dawn prayer, put his head through the door of the mosque and said, ‘Who has called me—that is, who has found—my red camel?’ The Prophet (peace and blessings be upon him) replied, ‘May you never find it, may you never find it, may you never find it! These mosques were built only for the purposes for which they were built.’”
This narration is from Buraydah (may Allah be pleased with him). Muslim records it—the first additional wording is his—as do Ibn Mājah, al-Ṭiyālisī, and Aḥmad; Ibn al-Sunnī and al-Bayhaqī likewise transmit it through several chains from ʿAlqamah ibn Murthad, from Sulaymān ibn Buraydah, from his father. The second and third supplementary phrases are found in another report of Aḥmad, and are also attributed to him.
