The Messenger of Allah ﷺ slept until he was breathing audibly, then he got up and prayed.
حدثنا عبد الله بن عامر بن زرارة حدثنا يحيى بن زكريا بن أبي زائدة عن حجاج عن فضيل بن عمرو عن إبراهيم عن علقمة
أن رسول الله ﷺ نام حتى نفخ ثم قام فصلى
[Hasan] Ahmad narrated it in his Musnad (1/426) from the hadith of Yahya, using this route, though Hajjaj bin Artah transmitted it using the ambiguous form "an" rather than a clear connective. The preceding hadith serves as a corroborating witness for it, and both have other corroborating witnesses as well.
