Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrates that a man asked the Prophet (peace and blessings be upon him): "I performed the sacrifice before shaving my head, is there any harm?" He replied: «اب سر منڈوا لو، کوئی حرج نہیں۔» Another man said: "I shaved my head before performing the sacrifice, is there any harm?" He replied: «اب قربانی کر لو، کوئی حرج نہیں۔» Another said: "I performed the sacrifice before throwing the pebbles, is there any harm?" He replied: «اب کنکریاں مار لو، کوئی حرج نہیں۔»
