Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "If any obstacle comes before me, I will do what the Noble Prophet (peace and blessings be upon him) did when the disbelievers of Quraysh stood between him and the House of Allah, and he shaved his head and returned. I make you witnesses that I have made the intention for Umrah." Then the narrator mentioned the complete hadith.
