Musannaf Ibn Abi Shaybah 3510 — Those who said: when one hears

Abd al-Rahman bin Abi Layla said: Sayyiduna Ibn Umm Maktum (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) and said: "The land of Madinah has many crawling creatures and marshy places; is there a concession for me to pray Isha and Fajr in my house?" He (peace and blessings be upon him) said: "Do you hear 'Hayya 'ala al-salah' (Come to prayer) and 'Hayya 'ala al-falah' (Come to success)?" He said: "Yes." He (peace and blessings be upon him) said: "Then you must come to the prayer."
