It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that Sayyiduna Umar (may Allah be pleased with him) said: Although Hajj Tamattu' is the Sunnah of the Prophet (peace and blessings of Allah be upon him), I fear that people will spend the night with their wives under the trees of Pilu and then in the morning get up and make the intention for Hajj.
