سنن النسائي 729

It was narrated that 'Abdul-Malik bin Sa'eed said:"I heard Abu Humaid and Abu Usaid say: 'The Messenger of Allah (ﷺ) said: "When any one of you enters the Masjid, let him say: 'Allahumma aftahli abwaba rahmatik (O Allah, open to me the gates of your mercy). And when he leaves let him say: Allahumma inni as'aluka min fadlik (O Allah, I ask You of Your bounty)

Rapporté par 'Abdul-Malik bin Sa'eed : J’ai entendu Abu Humaid et Abu Usaid dire : Le Messager d’Allah (ﷺ) a dit : "Quand l’un de vous entre dans la mosquée, qu’il dise : 'Allahumma aftahli abwaba rahmatik' (Ô Allah, ouvre-moi les portes de Ta miséricorde). Et quand il sort, qu’il dise : 'Allahumma inni as’aluka min fadlik' (Ô Allah, je Te demande de Ta grâce)
