"The Messenger of Allah performed Qaran for Hajj and Umrah, so he performed one Tawaf for both of them."
Jami` at-Tirmidhi Book 9, Hadith 141
← Previous Hadith "I heard the Prophet saying: 'Whoever performs Hajj to this House, or Umrah, then let the last of his acts be at the House'" So Umar said: "May your hand be humiliated! You heard this from the Messenger of Allah but did not inform us of it?"

Jami` at-Tirmidhi Book 9, Hadith 140 Next Hadith → The Messenger of Allah said: "Whoever assumes Ihram for Hajj and Umrah, then it is acceptable for him to perform one Tawaf and one Sa'I for them both, until he exits Ihram for both of them together."

Jami` at-Tirmidhi Book 9, Hadith 142
