1700 – Al-Sāʾib ibn Yazīd (may Allah be pleased with him) said: “I was in the mosque when a man pelted me with pebbles. I looked and it was ʿUmar ibn al-Khaṭṭāb (may Allah be pleased with him). He said, ‘Go and bring me those two men.’ I brought them to him and he asked, ‘Where are you from?’ They replied, ‘From Ṭāʾif.’ He said, ‘Had you been from this city I would have punished you severely, for you raise your voices in the mosque of the Messenger of Allah (peace and blessings be upon him).’” Narrated by al-Bukhārī.

Explanation
The author (may Allah have mercy on him) states in his Riyāḍ al-Ṣāliḥīn, under the chapter “The reprehensibility of raising voices in the mosques, announcing lost property, buying, selling, and similar acts”:

Allah, exalted is He, has attributed the mosques to Himself, saying, “And who is more unjust than one who prevents [others] from the mosques of Allah from mentioning His Name therein” (Q 2:114). The Prophet (peace and blessings be upon him) likewise linked them to his Lord when he said, “Do not prevent the female servants of Allah from the mosques of Allah.”

Allah has also clarified that these mosques are houses in which His Name is remembered: “In houses which Allah has permitted to be raised and wherein His Name is mentioned, He is glorified therein morning and evening by men whom neither commerce nor sale distracts from the remembrance of Allah, the establishment of prayer, and the giving of zakāh” (Q 24:36-37).
