Hadith 1785 - Bab 358 (Undesirability of Leaving the Mosque without offering Salat (Prayer) after the Adhan has been Proclaimed)
Chapter 18 (The Book of the Prohibited actions)

Abu Sha'tha' said: We were sitting with Abu Hurairah (May Allah be pleased with him) in the mosque when the Mu'adhdhin proclaimed the Adhan. A man stood up in the mosque and started walking out. Abu Hurairah (May Allah be pleased with him) stared at him till he went out of the mosque. Upon this Abu Hurairah (May Allah be pleased with him) said: Indeed, this man has disobeyed Abul-Qasim (Peace be upon him).

Aboushsha"thà rapporte: «Nous étions assis avec Abou Hourayra (das) quand le Muezzin lança l"appel à la prière. Un homme sortit alors de la mosquée. Abou Hourayra le suivit des yeux jusqu"à ce qu"il en sortît. Il dit: «Quand à celui-là, il a désobéi à Abou Al Qàsem (bsdl)». (Rapporté par Moslem)
