[Machine] "That the Messenger of Allah ﷺ said: 'The key to prayer is ablution, its sanctification is Takbeer, and its permission is Tasleem.' Abu Umar ad-Dareer exclusively reported this, as claimed by Ibn Saad, and many of the scholars have followed him. Habban bin Hilal also narrated it from Hassan, and it is Hassan who exclusively reported it. Abu Nasr Umar bin Abdul Aziz bin Qatadah narrated it, Abu Amr reported on the authority of Abu al-Abbas ibn Abi ad-Dummek, who reported on the authority of Abdullah al-Ayshiyy, who reported on the authority of Hassan bin Ibrahim, who reported on the authority of Abu Sufyan, who reported on the authority of Abu Nadrat, who reported on the authority of Abu Sa'id, who said: The Messenger of Allah ﷺ said: 'The key to prayer is ablution, its sanctification is Takbeer, and its permission is Tasleem.' This is the narration that Abu Sufyan Tarif as-Sa'di preserved, and the hadith of Abu Sa'id is often mentioned."
