Your Prophet ﷺ was commanded with fifty prayers, then he negotiated with your Lord until He made them five prayers.
حدثنا أبو بكر بن خلاد الباهلي حدثنا أبو الوليد حدثنا شريك عن عبد الله بن عصم أبي علوان
أمر نبيكم ﷺ بخمسين صلاة فنازل ربكم أن يجعلها خمس صلوات
[Sahih] Mizzi narrated it in Tahzib Kamal (15/307, 308), in the biography of Abdullah bin Isam, from the hadith of Abu Walid Hisham bin Abdul-Malik, through this same chain. Sharik was mentioned earlier, page 149, narrating with "an", and his teacher is disputed. Their hadith has corroborating witnesses in meaning. See the previous hadith.
